Wonderful character development!

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

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