I was a bit disapointed by this. Not that it was bad per se but it was being billed as "the best movie of the year" or some shit.
I didn't dig the humor. I maybe laughed twice, one of which was the line "I bought another Sonic Youth album and it sucked. It's just noise". It's funny cause it's true.
Of course the critics are having orgasms about how clever and "smart" the humor is. I guess in a way it is but I really can't stand humor that's based entirely in cynicism. And 95% of the humor is about mocking middle-class white suburbia. Of course you got your razor sharp teens and your bumblingly clueless grown-ups. This kind of humor has done before (to death, IMO) and done better (like in, say, Election).
Now part of me thinks "Hey, maybe I don't like it because I'm not the target demographic anymore". But I dunno. I liked Superbad. I thought Superbad was ten times better than this.
However, I did like the last 30 minutes when it turned into more of a serious drama. However, that's probably the point where the 16 year olds started to think it got boring. Again, maybe I'm not the target demographic.
