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.

After playing with our expectations, this turns out to be a very different sort of film.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

This is a coming of age storyline that you've seen in one form or another for decades. It takes a truly unique voice to make yet another one worth watching.
