I came across this last night and I think it looks really good.
I love western/cowboy stuff (Open Range, Appaloosa, The Hateful Eight, True Grit, Silverado, The Homesman, Bone Tomahawk, Lonesome Dove, The Quick and the Dead, 3:10 to Yuma, Tombstone, that Jesse James movie with Brad Pitt, anything with Sam Elliot and his 14" mustache, all the Eastwood stuff, etc.). If it's got people with hats riding horses and shooting each other, I'm gonna watch it!
This is right in that sweet zone.
I've enjoyed Tim Blake Nelson in everything I've ever seen him in, and it's great to see him front-and-center and the lead in such a thing (I know there was that Buster Scruggs movie a while back; this looks a bit more grim/realistic).
