Good story, Not enough for a whole film

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

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.

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.
