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

Your blood may run cold, but you now find yourself pinioned to the story.

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
