That is possibly the best coming-of-age comedy I've ever seen, and certainly the best I've seen in the last decade. Also one of the laugh-out-loud funniest movies I've ever seen. And furthermore, hands down the best depiction of high school insecurities and such I've ever seen - yes, it's caricaturized, and some things are flatly a bit unbelievable - but to give it credit, the caricatures based visibly on real and recognizable types and situations.
It's also the best "holy fuck, this night JUST NEVER ENDS" movie since After Hours.
GO SEE IT!
