Parents need to know that this movie includes some strong language, drinking and smoking (scenes in a bar, character drinks to drown his sorrows), drug humor, brief barf and toilet humor, and sexual references and situations. But the movie has a positive message about sexual values, as Rosalie's decision not to have sex with Tad is an important part of his developing respect for her and wanting to get to know her better.
I watched this movie with a bunch of my friends and we enjoyed it. It's not great and there are some sexual refrences and scenes, but other than that it's pretty appropriate for kids 11+.
