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

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

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

.Like the great film, it's made with a great deal of visible affection both in front of and behind the camera.
