Why so much hype?

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

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.

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.
