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

While it doesn't offer any answers, it both thrills and makes you think.

what a terribly boring film. I'm sorry but this is absolutely not deserving of best picture and will be forgotten quickly. Entertaining and engaging cinema? No. Nothing performances with flat faces and mistaking silence for subtlety.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
