Simple and well acted, it has tension enough to knot the stomach.

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

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.
