It's got an equally good shot at making us care about these imperfect pretty girls."[90] A writer on Terror Hook has stated that " 'Pretty Little Liars' gets off to a very promising start. Great production all around, the writing keeps the viewer on their toes, and the acting just reinforces it. The overall mystery of the show in the end is dark and unpredictable, even stepping into the slasher film realm."[91] The New York Post gave the show three out of five stars, stating, "OK, so we've established that there is no socially redeeming value in this series and that your kids shouldn't watch it if they are too young and impressionable. But if you can distract them enough to miss the first 15 minutes, the show isn't half-bad. Actually, it is half-good, if that makes sense."[92] The Los Angeles Times wrote that the series is "one of those shows that manages to mildly, and perhaps unintentionally, spoof its genre while fully participating in it, and that's not a bad thing at all."[93]

Entertainment Weekly had a less favorable review, giving the show a letter grade of "D−", saying, "Imagine the pitch for Liars: It's I Know What You Did Last Summer meets Gossip Girl, but like not so subtle." It went on to say that the plot "hits every racy teen entertainment mark so hard (everyone's hair is so full—of secrets!) that it feels like the only thing missing is a visit from the ghosts of Jennifer Love Hewitt and Freddie Prinze, Jr."[94] The Hollywood Reporter compared the show to those on The CW and noted, "Sure, there's a lot here that sustains more eye-rolling than interested stares, but a little patience might be warranted."[95]
