Absolutely the worst movie.

This is a must-see and one of the best documentaries - and films - of this year.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

Watching it is like watching the spectacle of a class clown at their best: you laugh at their jokes, instigate their defiance, and "ooooh" when they get in trouble.
