I will tell you that we almost turned it off after 10 minutes because it seemed so corny and sophomoric. We couldn't understand why it won so many awards. I'm glad we kept on because once you get past the first 20 minutes, you realize that the whole movie is tongue-in-cheek. And it's absolutely hilarious and fun. Nothing more - don't look for deep meaning here. It's just plain, simple, ridiculous fun.
