Duke was too unsympathetic
He was a one-dimensional badass, that's it. He got the happy ending, even though he didnt deserve it.
Robert's wife was the most sympathetic character in the movie, but she lost everything and has to resort to being a prostitute. The daughter's fate is unknown(her last moment in the movie was sort of dark), and everyone else who even was slightly likable died.
So I was disapointed with the ending.
