I watched it twice. The camera work of first 30 minutes are so are pretty great. But I remember feeling disappointed with parts of the middle of the movie up until the pursuit at the end. The worst scene is where he rides off the cliff on the horse. It's trash. I will probably watch it again though in a few years. I do love the fade to credits at the end with the breathing after he sees his wife.
There's getting mauled by a a bear and then there's American Indians have spaghetti aim like a Star Wars storm trooper against one guy who is sleeping when they approach. It really jumps the shark there for me. I don't know the original book but it seemed like a convenience to get; HORSE DIES therefore GET INSIDE HORSE. Obviously can't have him kill the horse to survive because people don't like animals getting killed.
The CGI is awful!
We're expected to believe they just up and left assuming he died from the fall even after he shot them, but of course "there's a storm rolling in so they had to leave him". I think it could've been done differently. No Indians, just the freeze coming and the horse meeting its end naturally?
The soundtrack is pretty perfect for the movie. Really surprised Ryuichi Sakamoto was involved.
