In truth, there is barely enough story here to make a film.

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

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.

Blistering performances.
