This movie is the proof that the world is becoming a sick and dumb place

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,

Exactly the movie you think it is, but not the movie you want it to be.
