The obvious motive behind every film is to make money. Not all are successful at this. Sometimes a film, like this one, also has good performances. This film was carried by the performances and elevated the material. And comparing this to F9-11 is a joke. For one Moore himself has come out and basically said it is propaganda. The only people saying so about Million Dollar Baby are thos who are biased against a plot element. Is every film with drug use a pro-drug propaganda film?
I find what the film is trying to say is that it is never too late to a) acheive your goals and b) do not close yourself off because you might find fulfillment in a part of your life you have given up on. This film is about their relationship. The entire span of it. The end of a relationship is saying good bye. The way they chose to do it is assisted suicide. It is a questionable act, but it is a powerful one, and I feel used to show how deeply Clint thinks about the girl. He was very horrified about doing so at first, and was never happy while doing it. And we are not led to believe afterwards that he finds peace.
I am amazed that no one has seized on the film being anti-welfare. If it is pro-euthanasia at least someone in the film speaks out against it. The only thing we see about welfare is the scumbag mom.
