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.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

Story: It's very simple but honestly that is fine.
