I heard some really terrible things about this movie, and while it's nothing groundbreaking, it's also nowhere near anything more offensive than what I watched when I was a teenager.
21 & Over follows suit in the classic jock-teen-sex-boozing-frat mold as any of the American Pie movies, and actually comes close to achieving several funny lines.
I like the whole idea that the people you were friends with during school often aren't your friends after it, however the movie does cop out a bit with a happily-ever-after ending.
What do you want, it's booze, buds and barfing. You were expecting Kubrick?
