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

I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

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

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.
