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

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.

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

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