It's entirely possible that sending the audience out feeling lousy was intentional

One of the most extraordinary films you will see this year. Take that as you want.

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.

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.
