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.

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

Story: It's very simple but honestly that is fine.
