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.

A movie that not only functions as a solid scarefest but a razor-sharp satire.

Amazing worth wacthing. So good. Biased but well made with many good points.
