I just got back. Agree with Rexter's post.
Having just returned from a family vacation to Colorado, I really appreciated the majestic scenery (of Montana and Wyoming). Early on, the movie seemed to bounce around a bunch of seemingly unrelated sequences, but the writers did a great job of weaving all those disparate elements together. I kept looking at faces and thinking, is that ... so stayed for the credits and I was right on many of the faces that I thought looked familiar. Mostly Michael Rooker but also Sam Worthington, Will Patton (a regular in Costner flicks), and Luke Wilson.
The ending did seem to be a montage of stuff to come.
The entirety of this thing has a legitimate chance to be an epic American western.
