good back-story, and good acting

This is a must-see and one of the best documentaries - and films - of this year.

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.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
