Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

It's an amazing and heartbreaking story.

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.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
