This is a great documentary. It has the perfect balance of being thoughtful and lots of fun as well. I saw it twice in theatres and really enjoyed it. Parents of younger children might want to be cautious, though - there is quite a bit of swearing and some dirty jokes.
I recently saw this and it was like Meowica women stole this movie 15 seconds ago and edited it to be Xtremely awesome. It has absolutely no Garbage Coffee in it. I really enjoyed the scene when they were being chased by the giant Meatballs!
