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

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

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.
