Cliches, tropes, and instagram filters. Great cast and entertaining enough to have on in the background, which is why it is getting 2 stars. Otherwise pretty ridiculous.
Writing completely ignores weather (similar to The Revenant) and injuries. Somehow debilitating accidents and injuries are completely gone or ignored in the next scene. Canted cinematography and crazy filters make it difficult to watch.
Would've been a create premise and story to create, but the cliches and ridiculous movie and tv tropes took away all semblance of realism, not to mention the seemingly rapid fire bows that the Natives used. Disappointing addition to the Western genre. Save yourself some time and go re-watch 1883.
