The Shootist is one of the rare great cowboy movies since the hippy culture destroyed...well just about everything, in particular westerns.
Just a great movie on a number of levels, I personally like the quote:
"I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them."
I think that most of us live our lives with this in mind.
