Another giggly gross-out comedy for teenagers, this one somewhat better than most by virtue of a more satisfying ending. Four horny high school seniors seeking to lose their virginity before graduation encounter lots of embarrassing situations en route; once the female characters start to take matters in hand, things proceed more purposefully. Written by Adam Herz and directed by Paul Weitz, both newcomers; with Jason Biggs, Shannon Elizabeth, Alyson Hannigan, Chris Klein, Natasha Lyonne, Thomas Ian Nicholas, Tara Reid, Seann W. Scott, Mena Suvari, Eddie Kaye Thomas, and Eugene Levy. (JR)
