Hmm...I really disagree with CSM's review on this one. I thought it was funny, had likeable characters, and surprisingly smart for a teen movie. Also, they really overreacted with the content--Orange County does sometimes push the PG-13 rating to the limit, but it's perfectly fine for teenagers.
Such a funny movie, I think it's fine to watch it with younger teens but as long as there's a parent there supervising to skip the sexual parts lol.
Then again it's more relateable to high school kids, so who knows if the younger kids can even relate & actually enjoy it. *shrugs shoulders.
