If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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 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.

It's easily one of the freshest, sharpest and most enjoyable films of this year.
