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,

By the time the dramatic fireworks start popping off, each one feels earned.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
