Eapking is dead on. I just got back from seeing it at a Noon showing. The humor is dark, the dialogue is great, and very period specific it seems. Xring is right about JW and Jeff bridges does NOT even attempt to play JW. He's likable, but he's a grizzled, drunk bounty hunter plain and simple. Jeff plays Rooster, not Rooster plays JW.
The cinematography is excellent and the movie is just well done over all. I will say this much and for those of you that have seen the original it won't be a spoiler, but just in case it is.........
SPOILER:
When Rooster and Lucky Ned face down at the end in this version, it's kind of scary. Barry Pepper just looks and sounds evil. I remember watching the original and hearing JW and Robert Duvall's exchange and it's just cool dialogue, like there's no chance Rooster won't win. In this one when the lines were exchanged and the music cued up I got worried for a second.
I really urge you guys to separate the 69 version and this one and give it a shot. It's a really, really great western.
