I was looking for a movie with a non-violent role model, and I remembered this one revolves around the main character choosing to walk away from his violent potential. Unfortunately, this moment is so subtle that most younger kids miss the point completely.
That being said, there are a lot of positives here: for instance, the main character is afraid of the changes he's going through, and tries to hide them from his father - but eventually the father breaks through and he sees that talking to his parents was the right thing to do (a rare occurrence in teen movies.)
I wasn't prepared for the wild party scene, where kids get drunk and are paired off in various highly-sexualized situations (two were stripped to their underwear, tied together, and covered with whipped cream.) Fortunately, the embarrassment of the affected characters so horrified my son that it made for a good talking point about wild parties and the effects of alcohol on good choices.
In another scene, the head cheerleader takes off her clothes (you see her naked back) and it's implied she has sex with the main character. It's made clear that she did so solely to boost her popularity, and she treats him cruelly shortly afterwards. It's difficult to disentangle this behavior from the intended message, but it, again, led to a good conversation about people liking you for who you are and not what they can get out of you.
In short, I would suggest that this movie accompany a conversation about behavior and consequences.
