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

At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.

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

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