It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

Blending excellent reporting and strong storytelling, this is a disturbing film truly stranger than fiction

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

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.
