On the review aggregator website Rotten Tomatoes, the series has an average rating of 35%.[51] On Metacritic, the weighted average rating for all seasons except the last one is 60 out of 100, based on 38 critic reviews, indicating "mixed or average reviews".[52]

Rotten Tomatoes reports that 77% of 65 critic reviews are positive for the first season, and the average rating is 7.1/10. The website's critical consensus reads, "13 Reasons Why complements its bestselling source material with a gripping look at adolescent grief whose narrative maturity belies its YA milieu."[46] Metacritic assigned a score of 76 out of 100, based on 17 critics, indicating generally favorable reviews.[47]

Jesse Schedeen of IGN praised 13 Reasons Why, giving it a 9.2 out of 10, stating that the series is "a very powerful and hard-hitting series" and "ranks among the best high school dramas of the 21st century".[53] Matthew Gilbert of The Boston Globe gave a glowing review for the series, saying, "The drama is sensitive, consistently engaging, and, most importantly, unblinking."[54] Maureen Ryan of Variety asserts that the series "is undoubtedly sincere, but it's also, in many important ways, creatively successful" and called it "simply essential viewing".[55] Leah Greenblatt of Entertainment Weekly gave the entire season a score of B+, calling the series "a frank, authentically affecting portrait of what it feels like to be young, lost and too fragile for the world".[56] Daniel Feinberg of The Hollywood Reporter also praised the series, calling it "an honorably mature piece of young-adult adaptation", and citing its performances, direction, relevance and maturity as some of the series' strongest points.[57]

The acting, particularly that of Katherine Langford as Hannah and Dylan Minnette as Clay, was frequently praised in reviews. Schedeen of IGN praised the cast, particularly Minnette and Langford, stating: "Langford shines in the lead role ... [and] embodies that optimism and that profound sadness [of Hannah's] as well. Minnette's Clay is, by design, a much more stoic and reserved character ... and does a fine job in what's often a difficult role."[53] Gilbert of The Boston Globe praised the chemistry of Langford and Minnette, saying that "watching these two young actors together is pure pleasure", while Schedeen of IGN also agreed, saying that they are "often at their best together, channeling just the right sort of warm but awkward chemistry you'd expect from two teens who can't quite admit to their feelings for one another". Feinberg of The Hollywood Reporter also praises both actors: "Langford's heartbreaking openness makes you root for a fate you know isn't possible. The actress' performance is full of dynamic range, setting it against Minnette's often more complicated task in differentiating between moods that mostly go from uncomfortable to gloomy to red-eyed, hygiene-starved despair."[57]

Ryan of Variety also gave praise to not only the two leads, but also the supporting cast of actors, particularly Kate Walsh's performance as Hannah's mother, which Ryan describes as "career-best work".[55] Positive mentions from various critics, such as Ryan, Feinberg and Schedeen, were also given to the supporting cast of actors (most particularly Alisha Boe, Miles Heizer and Christian Navarro's respective performances as Jessica, Alex and Tony). Liz Shannon Miller of Indiewire, who enjoyed the series and gave it a positive score of B+, gave praise to the racial, gender and complex diversity of its supporting cast of teens.[55][53][57][58]

Another aspect frequently mentioned within reviews was the series's mature and emotional approach to its dark and adult subject matter. This was favorably reviewed by critics, such as Miller of Indiewire, particularly her statement that "the adult edges to this story ring with honesty and truth."[58] Miller, and Feinberg of The Hollywood Reporter, also stated that the series can be difficult to watch at times,[57] while Schedeen of IGN states that it is "an often depressing and even uncomfortable show to watch ... a pretty emotionally draining experience, particularly towards the end as the pieces really start to fall into place."[53]

Critics also praised several other aspects of the series. Feinberg highlighted the series' directors, saying: "A Sundance-friendly gallery of directors including Tom McCarthy, Gregg Araki and Carl Franklin keeps the performances grounded and the extremes from feeling exploitative",[58] while Gilbert of The Boston Globe praised the storytelling: "The storytelling techniques are powerful ... [as it] builds on the world established in the previous hour, as we continually encounter new facets of Hannah's life and new characters. The background on the show keeps getting deeper, richer."[54]

Conversely, the series has also received criticism over its portrayal of teen angst. Mike Hale of The New York Times wrote a critical review, writing, "the show doesn't make [Hannah's] downward progress convincing. It too often feels artificial, like a very long public service announcement." He also criticized the plot device that has Clay listening to the tapes one by one instead of all in one sitting like the other teens did, which Hale felt was unbelievable: "It makes no sense as anything but a plot device, and you'll find yourself, like Clay's antagonists, yelling at him to listen to the rest of tapes already."[59]

Writing for The Guardian, Rebecca Nicholson praised some aspects of the series, including the performances from Minnette and Walsh, but was troubled by much of the plot, writing, "a storyline that suggests the love of a sweet boy might have sorted all this out added to an uneasy feeling that stayed with me". Nicholson was skeptical that the series would appeal to older viewers, unlike other series set in high school such as Freaks and Geeks and My So-Called Life: "It lacks the crossover wit of its forebears ... It's too tied up in conveying the message that terrible behaviour can have horrible consequences to deal in any subtleties or shades of feeling. It's largely one-note – and that note is horrifying. 'It has to get better,' implores one student towards the end, but given its fairly open ending, an apparent season two setup, it does not seem as if there's much chance of that happening."[60]

The Washington Post television critic Hank Stuever wrote a negative review, finding 13 Reasons Why "contrived" and implausible: "There are 13 episodes lasting 13 super-sullen hours – a passive-aggressive, implausibly meandering, poorly written and awkwardly acted effort that is mainly about miscommunication, delivering no more wisdom or insight about depression, bullying and suicide than one of those old ABC Afterschool Specials people now mock for being so corny." He also wrote that he found Hannah's suicide tapes "a protracted example of the teenager who fantasizes how everyone will react when she's gone. The story ... strikes me as remarkably, even dangerously, naive in its understanding of suicide, up to and including a gruesome, penultimate scene of Hannah opening her wrists in a bathtub."[61]

David Wiegand of the San Francisco Chronicle gave the series a tepid review, saying that it was plagued by character inconsistencies, particularly in Hannah's character. He praised Langford's "stunning performance" but noted, "There are times when we simply don't believe the characters, when what they do or say isn't consistent with who we've been led to believe they are ... At times, [Hannah] is self-possessed and indifferent at best to the behavior of the popular kids. At other times, though, relatively minor misperceived slights seem to send her into an emotional tailspin. No doubt, teenagers embody a constant whirl of conflicting emotions, but the script pushes the bounds of credibility here and there." He noted that overall, the series worked: "The structure is gimmicky and the characters inconsistent, but there are still at least 13 Reasons Why the series is worthy."[62]

The second season received generally negative reviews from critics, with criticism aimed at the writing; many declared the season unnecessary and boring.[63][64] On Rotten Tomatoes, 28% of 53 reviews are positive, with an average rating of 5.3/10. The site's critical consensus states, "By deviating from its source material, 13 Reasons Why can better explore its tenderly crafted characters; unfortunately, in the process, it loses track of what made the show so gripping in the first place."[48] On Metacritic, the season has an average score of 49 out of 100, based on 16 critics, indicating "mixed or average reviews".[49]

Catherine Pearson from Digital Spy wrote a negative review, calling the season "even more problematic" than the first. She ends the review saying that, "Unrelenting depression seems to shroud the season, briefly lifted only to collapse back down as the show's thirteenth episode, once again, delivers a deeply disturbing scene of suffering."[65] Jordan Davidson from The Mighty wrote that he "felt sick" after watching the final episode of the season.[66]

A scene in which the character Tyler Down (Devin Druid) is attacked and sexually assaulted with a mop handle by bully Montgomery De La Cruz (Timothy Granaderos) during the finale also caused controversy from fans and critics of the series, with some describing it as "unnecessary" and "traumatizing".[67] Series showrunner Brian Yorkey defended the scene, saying that it was included in an attempt to "tell truthful stories about things that young people go through in as unflinching a way as we can".[68]

The third season was met with overwhelmingly negative reviews, with criticism aimed at the screenplay for poor execution of its topics, including the rape of Tyler in the final episode of the previous season,[69][70] the new character of Ani,[71] the sympathetic redemption of Bryce,[72] genre changing from drama to mystery, and the conclusion. However, the technical aspects and the performances received some praise.[73]

Rotten Tomatoes reports that 11% of 18 reviews are positive, and the average rating is 1.4/10. The site's critical consensus reads: "13 Reasons Why attempts to break away from its first two seasons only to become a melodramatic mess of a murder mystery."[50] On Metacritic, the season has an average score of 23 out of 100, based on 4 critics, indicating "generally unfavourable reviews".[12]

Like the previous two seasons, the fourth and final season also received negative reviews. The writing and story remained the primary criticized aspects, while the ending was met with a divided reception.[74][75][76][77]

On Rotten Tomatoes, 25% of 12 reviews are positive, with an average rating of 5.3/10. The site's critical consensus states: "13 Reasons Why closes with a chaotic final chapter that betrays what little dignity remained in the tragic lives of its central teens."[13] Episode six, in which the school runs a "drill" where the students are made to believe there is an active shooter was heavily criticized, with many fans and critics describing the episode as "too realistic", "triggering" and "traumatising", although some reviewers noted that the show had tackled a topic that was relevant to many American school students.[78][79] The storyline of Justin Foley being diagnosed with and killed by complications of AIDS generated controversy, with many calling it "unfair".[80] Minnette defended the decision, saying that he and Flynn had pushed showrunner Brian Yorkey to kill off Justin, as they "both felt that it would have the biggest emotional impact on the series as [Justin] had the most emotional impact out of all of the characters".[81]

The marketing analytics firm Jumpshot determined the first season was the second-most viewed Netflix season in the first 30 days after it premiered, garnering 48 percent of the viewers that the second season of Daredevil received, which was the most viewed season according to Jumpshot. The series also showed an 18 percent increase in week-over-week viewership from week one to week two. Jumpshot, which "analyzes click-stream data from an online panel of more than 100 million consumers", looked at the viewing behavior and activity of the company's U.S. members, factoring in the relative number of U.S. Netflix viewers who watched at least one episode of the season.[82] According to Nielsen, the premiere episode of the second season drew 6.08 million viewers in the U.S. in the first three days of its release.[83] It also revealed that a significant part of its audience were young – aged 34 or younger (75%) – and female (65%) – with males representing 35 percent of viewers.[83] The second season became the eighth most watched English-language television series on Netflix, with 496.1 million hours viewed.[84]

Several health professionals, educators and advocates linked the show to self-harm and suicide threats among young people. This community also expressed major concerns about the series romanticizing suicide, not providing adequate resources at the conclusion of each episode, targeting a young vulnerable audience, and painting mental health professionals as unhelpful and not worth seeing.[104][105][106] Mental health experts are also educating the general public on what to do in the situations Hannah Baker goes through, disseminating accurate information surrounding teen suicide, depression, and youth that experience traumatic events through research surrounding the show and mental health resources for help-seeking youth.[114]

The release of 13 Reasons Why corresponded with between 900,000 and 1.5 million more suicide-related Google searches in the United States, including a 26 percent increase in searches for "how to commit suicide", an 18 percent increase for "commit suicide", and a 9 percent increase for "how to kill yourself".[115] After an initial spike in calls to the Crisis Text Line after the first episode, there was an overall reduction in crisis call volume for the remainder of the series.[116] Although the link between searching for suicide information and suicide risk is unclear,[117] increases in self-harm admissions to one children's hospital were observed.[118][119][120][121][122]

The superintendent of Palm Beach County, Florida schools reportedly told parents that their schools had seen an increase in suicidal and self-harming behavior from students, and that some of those students "have articulated associations of their at-risk behavior to the 13 Reasons Why Netflix series".[123]

The Australian youth mental health service for 12–25 year-olds, Headspace, issued a warning in late April 2017 over the graphic content featured in the series, due to the increased number of calls to the service following the series' release in the country. However, Netflix demonstrably complied with the Australian viewer ratings system by branding the series as "MA15+" when streamed via its own interface. They accompanied its presentation with additional warnings and viewer advice, and ensured that counselling referrals were included and not easily skipped at the conclusion of each episode. Each warning voice over is read by a different cast member at the end of the episode, with Katherine Langford reading in her native Australian accent in her voice-overs.[124][125][126]

In response to the graphic nature of the series and New Zealand's high youth suicide rate, which was the highest among the 34[lower-alpha 1] OECD countries during 2009 to 2012,[128][129] the Office of Film & Literature Classification in the country created a new rating, "RP18", allowing individuals aged 18 and over to watch the series alone and those below having to watch it with supervision from a parent or guardian.[130][131]

In April 2017, the National Association of School Psychologists (NASP) in the United States released a statement regarding the series, saying: "Research shows that exposure to another person's suicide, or to graphic or sensationalized accounts of death, can be one of the many risk factors that youth struggling with mental health conditions cite as a reason they contemplate or attempt suicide."[132] NASP sent a letter to school mental health professionals across the country about the series, reportedly a first for NASP in response to a television series.[133] The following month, the United States Society of Clinical Child and Adolescent Psychology (SCCAP) released a statement also noting how strongly the series may serve as a trigger for self-injury among vulnerable youth. They lamented the depiction of mental health professionals as ineffective for youth who have experienced trauma and may have been considering suicide.[134] The statement implored Netflix to add a tag following each episode with mental health resources, and a reminder that depression and suicidal thoughts can be effectively treated by a qualified mental health professional, such as a clinical child psychologist, using evidence-based practice.

Similarly, clinical psychologists such as Daniel J. Reidenberg and Erika Martinez, as well as mental health advocate MollyKate Cline of Teen Vogue magazine, have expressed concerns regarding the risk of suicide contagion.[135][136][137] However, Eric Beeson, a counselor at The Family Institute at Northwestern University noted that "it's unlikely that one show alone could trigger someone to attempt suicide."[132] Mental health professionals have also criticized the series' depiction of suicide itself, much of which violates widely promulgated recommendations for reporting on actual suicides or not depicting them in fiction, in order to not encourage copycat suicides.[138] The season finale, which depicts Hannah's suicide in graphic detail, has been particularly criticized in this regard.[139] Nic Sheff, a writer for the series, has defended it as intended to dispel the myth that suicides "quietly drift off", and recalled how he himself was deterred from a suicide attempt by recalling a survivor's account of how painful and horrifying it was.[140]

Executive producer Selena Gomez, in defense of the controversy surrounding the series, stated:

We stayed very true to the book and that's initially what Jay Asher created was a beautifully tragic, complicated yet suspenseful story and I think that's what we wanted to do ... We wanted to do it justice and yeah the backlash is gonna come no matter what. It's not an easy subject to talk about, but I'm very fortunate with how it's doing.[141]

The NASP statement also criticized the series' suggestion that bullying alone led Hannah to take her life, noting that while it may be a contributing factor, suicide far more often results from the bullied person having a "treatable mental illness and overwhelming or intolerable stressors", along with a lack of adequate coping mechanisms. Alex Moen, a school counselor in Minneapolis, took issue with the series' entire plotline as "essentially a fantasy of what someone who is considering suicide might have—that once you commit suicide, you can still communicate with your loved ones, and people will suddenly realize everything that you were going through and the depth of your pain ... That the cute, sensitive boy will fall in love with you and seek justice for you, and you'll be able to orchestrate it, and in so doing kind of still be able to live."[139] Other counselors criticized the depiction of Hannah's attempt to reach out to Mr. Porter as dangerously misleading, since not only does he miss obvious signs of her suicidal ideations, but says he cannot report her sexual assault to the police without her identifying the assailant. School counselors are often portrayed as ineffective or clueless in popular culture, Moen says, but Porter's behavior in the series goes beyond that, to being unethical and possibly illegal. "It's ridiculous! Counselors are not police. We don't have to launch an investigation. We bring whatever information we do have to the police", she told Slate.[139]

In May 2017, the Canadian Mental Health Association (CMHA) along with the Centre for Suicide Prevention (CSP) released a statement with similar concerns to the ones raised by NASP. CMHA believed that the series may glamorize suicide, and that some content may lead to distress in viewers, particularly in younger viewers. Furthermore, the portrayal of Hannah's suicide does not follow the media guidelines as set out by the Canadian Association for Suicide Prevention (CASP) and the American Association of Suicidology. CMHA and CASP did praise the series for raising awareness about "this preventable health concern," adding that, "Raising awareness needs to be done in a safe and responsible manner. A large and growing body of Canadian and international research has found clear links between increases in suicide rates and harmful media portrayals of suicide." Ways in which the portrayals of suicide may cause harm, according to CMHA and CASP, include the following: "They may simplify suicide, such as, by suggesting that bullying alone is the cause; they may make suicide seem romantic, such as, by putting it in the context of a Hollywood plot line; they may portray suicide as a logical or viable option; they may display graphic representations of suicide which may be harmful to viewers, especially young ones; and/or they may advance the false notion that suicides are a way to teach others a lesson."[142][143] A 2019 study in the Journal of the American Academy of Child and Adolescent Psychiatry found that the overall suicide rate among 10- to 17-year-olds increased by 28.9 percent in April 2017, the month immediately following the release of the first season. The study examined monthly suicide rates for that age range from January 2013 through December 2017, and the rate observed in April 2017 "was the highest monthly suicide rate of any month during the 5-year study period".[103]

Netflix responded to the criticism surrounding the series by adding strong advisory warnings prior to the ninth, twelfth, and thirteenth episodes in the first season, the first two due to rape and the last due to the suicide scene. In July 2019, before the release of season three, Netflix edited the suicide scene of the first-season finale. Originally, the episode included a bloody depiction of Hannah slitting her wrists in a bathtub.[144] However, it has been argued support to vulnerable viewers should be inspired by an ethical commitment toward the audience, rather than the moral panic for suicide contagion.[101]
