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

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.

One of those movie experiences that is so good it makes you realize you've been grading everything else on a curve.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
