I gave this film a 9 out of 10, because it was exactly what I expected it to be.

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

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

One of the most extraordinary films you will see this year. Take that as you want.
