It is a performances centric movie

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

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

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.
