A brilliant film that helped define a genre

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.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

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.
