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'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.

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

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
