I didn't think 3:10 to Yuma worked because there simply was no way Crowe could match the Glen Ford character. Ford was the epitome of "strong silent" hero. His persona made the sinister side to the villan better. And Van Hefflin really was a weaker man in morality and personality than Ford. Yuma still worked as a remake because it's a strong story IF you didn't see the first one when you were still a kid.
I think True Grit will be different, and i'm actually looking forward to it. Personally, I thought the movie with John Wayne was ham handed. It was a vehicle for an aging John Wayne. But, it didn't make any attempt to keep the flavor of the book's dialogue, and the general illiteracy/earthiness of the characters. From what I see the Jeff Bridges one does. I expect a pretty different film. While the number of stories is limited, characters are not. Crowe copied Ford, and I suspect Bridges will play it differently.
If you like westerns, you can get most of Have Gun Will Travel, Wagon Train, a slice of Gunsmoke and others on streaming netflix
