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

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

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
