A brilliant film that helped define a genre

What a freaking movie. So many twists and turns. Absolutely intense from start to finish.

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

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.
