I'll tell you why so serious

There's no way I can possibly love it entirely but I just think its ridiculously bad, but enjoyable at the same time.

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 a small, humorous movie in some ways, but it has a huge heart. What a nice experience.
