This would be a cute comedy about a bunch of likable characters, except that it's not very cute, not very funny, and the characters aren't very likable.
I felt that the movie was trying hard to be a hilarious teen comedy, while at the same time being serious about teen sexual angst and unrequited love. The result was that it fell between the two, and fell pretty hard, failing miserably at both.
People who come to this movie expecting some sort of laugh-a-minute romp will be disappointed by the occasional long attempts at seriousness, and will find themselves reaching for the fast-forward button.
Those who are looking for a semi-serious teen movie will just be turned off by the contrived and ludicrous situations created in an attempt at comedy.
Really, it's pretty bad. Unlike a previous reviewer, it is no mystery to me why this movie isn't better known.
