This movie was so-so. It had it's moments, but wasn't the greatest.

The film makes a home in your brain and the only cure is to see it again.

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 encouraging that the film ends so strongly.Otherwise, it wouldn't have been a particularly memorable film
