Very interesting film. Was caught on the premise when seeing the trailer but unsure as to what the outcome would be for the showing. As it turns out, it was a very good film.

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

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