Pretty good movie overall. First half was nothing special but it got better as it went along.

It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

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.

There's no way I can possibly love it entirely but I just think its ridiculously bad, but enjoyable at the same time.
