Unhappy w/ the Ending (Spoilers)

I loved this movie, though the end was a bit of a letdown for me. Anyone else wish that Arthur would have just died? Instead he goes on to almost brag about how all the bad money he has made went to help Finn. To me this kind of makes everything Arthur did for Finn worth that much less. The satisfaction of doing good deeds for another lies not in them knowing, but in watching them benefit from it. I felt as if the studio stuck this in there only to clarify further to the audience what Arthur had done. Arthur commenting that "Ragno did a hell of a job" should have been enough for the audience to understand. If left at that, it is as if Arthur accidently let a hint slip out, instead of intentionally bringing it up only for his own glorification. I really would have found it much more touching and sincere if Arthur had done his good deed for Finn with his only reward being the satisfaction that Finn 'made it' because of Arthur's selflessness. Even though Arthur himself may not have been happy with the decisions he made in his own life, he at least made one decision that sent somebody on the right path.

Once Arthur was dying on the subway, I was thinking, this is a great movie. It still was, even though I feel it should not have had this particular monologue at the end. Arthur dying with some last words should be included, but he should have simply shown regret for his own choices in life and happiness for Finn’s success, and then died with the comfort in knowing that his selflessness helped in Finn reaching a the life he couldn't have himself. Knowing his failure was Finn’s victory should be enough. I was ready to give it a 9, but probably a 7 or 8 now.

This of course is just personal preference, so what do you all think? If you like it the way it is, tell me why it works better for you that way.

I have not read the novel, does it end this way? Regardless, I feel it could have been better.
