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.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
