The rare teen comedy with serious raunch and heart, Premature is much, much better than any movie about ejaculation-triggered time travel has any right to be.
Premature is all of the embarrassing humiliation people who didn't lose their virginity fast enough felt and experienced throughout their entire lives packed into an hour and a half.
Beers' giddy feature embraces the sophomoric tradition of "Porky's"-era horny male humor with a warm, consistently funny attitude, like a scrappier version of "American Pie."
