Such a great film. I just saw it during my recent vacation in Utah. Kiwi director Andrew Dominik, did a lot of cool stuff with it. I see this film as a study on guilt from the perspective of both the esteemed criminal, Jesse James and the cowardly murderer, Robert Ford. Brad Pitt's performance is moving but Casey Affleck's is downright haunting. I liked the wide shots of western landscapes and the edge blurring camera effects that almost denote that the scene is only dimly remembered by its characters. The deeply voiced narratation from Hugh Ross adds a nice somber tone and the accents, costumes and set all seem incredibly authentic.
All in all, I highly recommend this one.
