I wanted to like it more than I actually did... But much of the humor totally escaped me and I walked out only mildly impressed.

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.

The film never slows down or bores, plunging from one harrowing sequence to the next.
