"Silence of the Slams" received positive reviews. Les Chappell from The A.V. Club gave the episode an "B" rating and wrote, "Consequently, I've known in the back of my head that we would return to the case-of-the-week format before too long, which we do with 'Silence Of The Slams.' While it's an approach that Grimm's never been terrible with, it's definitely ceased to be my favorite flavor of the show over the years, and the back-to-basics feel of events deflates the appreciable momentum of the last few weeks. Nothing about it is bad, but coming after a string of pretty terrific episodes it's hard for it to avoid letdown."[4]

Kathleen Wiedel from TV Fanatic, gave a 4 star rating out of 5, stating: "It was Case of the Week time in Grimm Season 5 Episode 13, with the team getting sucked into a case with a luchador being controlled by his own magical mask, which had been made from the face of a Balam."[5]

Lindi Smith from EW wrote, "What will Nick think if he finds out about Renard's involvement with Black Claw, and will this be yet another secret that Adalind keeps from him? There could also be trouble in paradise for Monroe and Rosalee since she has yet to tell him about Tony showing up in Portland while he was out of the country. Could all of this lying put the Scooby gang at odds during a time when sticking together is what they need most?"[6]

MaryAnn Sleasman from TV.com, wrote, "'Silence of the Slams' was a throwback Grimm, a methodical case-of-the-week episode with minimal spy games and Black Claw shenanigans, hardly any mention of the death-defying creation twig that Nick and Monroe risked life and limb for last week, or even much political maneuvering on Renard's part. He moped about his dead mayoral candidate and we got some verbal acknowledgement that Renard's brah was a 'good man' who was going to lift Portland out of that pesky hipster muck of craft beer, vegan bath bombs, and ridiculous/delicious donuts. Poor Portland. You'll never see a more wretched hive of scum and villainy — or so the Grimm take on politics seems to imply. Anyway, at the end of the day, we didn't freaking know the guy and he served to give Renard a plot point that has gone on entirely too long. Thank the TV gods that Renard finally decided to grab Adalind and go find their doomsday baby. Anything, to get him away from this tediousness."[7]

Christine Horton of Den of Geek wrote, "After the build-up to Grimm's 100th episode last week, the show's writers apparently felt the need to put a chokehold on some of the heavyweight storylines we've been treated to recently, and instead fall back on a regular Wesen-of-the-Week case. It's a shame the show is pulling its punches at this stage in the season when there's so much going on, least of all a global Wesen uprising and the discovery of an ancient artefact that can heal the sick and dying. But no, let's create an episode centred on the Portland wrestling scene!"[8]
