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

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

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.

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.
