Pretty good movie overall. First half was nothing special but it got better as it went along.

It's entirely possible that sending the audience out feeling lousy was intentional

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.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
