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

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.

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

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
