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.

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

Exactly the movie you think it is, but not the movie you want it to be.
