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

One of the best movies of the year! Incredible from the beginning to the end.

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
