For all the hype it got I was expecting a lot more!

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.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

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