What makes it different from others?

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.

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.
