Reviews `` Pilot '' was received with mixed opinions, although the series has gotten a more positive critique over its progression. Metacritic gave the pilot episode 52 out of 100, based upon 14 critical reviews. The New York Daily News gave the show a positive review, commenting that it `` makes most popular vampire romances look anemic '', while concluding, `` Pretty Little Liars could go in several directions, including mundane teen clichés. It 's got an equally good shot at making us care about these imperfect pretty girls. '' 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. '' 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 should n'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 is n't half - bad. Actually, it is half - good, if that makes sense. '' 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.
