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

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

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

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.
