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

I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
