A gross-out movie with a sweet story.
Parents need to know that this movie is gross, which is probably why it will appeal to fourth-graders everywhere. There's also some crude potty humor and mild profanity, as well as name-calling and bullying. But the message is straightforward and simple: It's okay to stand up for yourself, and sometimes, you have to eat worms (or in grown-up terms, do something you don't want to do) in order to gain the courage needed to get by in this crazy world.
