Parents need to know that this film deals with adult subject matter –- sexuality, economic class issues, and infidelity. There are strong messages here about the importance of friendship and family -- and of staying true to one's self.
This is a pretty decent movie that's worth watching. There's some strong profanity (including the f-bomb, used once in a sexual sense), and some mild to moderate sexual references, but not too much to worry about. Though the main characters do make mistakes and sometimes exhibit poor judgment, they clearly care about each other and their romantic interests and try to work their problems out.
