Three parents of teenage besties (Leslie Mann, John Cena and Ike Barinholtz), having gotten wind that their daughters (Kathryn Newton, Geraldine Viswanathan and Gideon Adlon, respectively) are planning to lose their virginity on prom night, launch a desperate campaign to stop them. The movie’s posters have the silhouette of a rooster, or “cock,” right above the title—“cock blockers,” get it? Hyuk, hyuk. That’s about the level of humor struck by Brian and Jim Kehoe’s script and Kay Cannon’s direction, but things aren’t quite as crude as they might have been, for which we can all be grateful. In fact, it’ll probably go unnoticed among all the penis and vagina jokes, but Barinholtz gives a very good performance as a rueful father whose bad choices have kept him from being the parent he wanted to be.
