I watched this a few nights ago with my sister and my parents. i thought it was hilarious! the characters are brian, who's the brain. he tried committing suicide cuz all the pressure that was on him. then there's claire, the princess, who's rich but has an awful family life. there's andrew, the jock, who wants to do whatever his dad tells him to. There's the basket case, Allison, who didn't talk until the middle of the movie but was really funny. Finally, the main character is John, a crack addict who's insane.
In the movie, there's a lot of bad language. There's also a lot of talk about virginity and stuff and John gets between Claire's legs. He also asks her some weird questions. But overall, it's a really good- and accurate- movie about knowing who you are. Don't show this to anyone under 12! Even 12 is a little young, but I'd say thats the age where it's your judgment.
