I enjoyed this in the end although it was slow to start. However it was difficult to follow as there was sadly a lot of mumbling and the story jumped about a fair bit.
Also a lot of it was inexplicably filmed in the dark, so along with the mumbling and the fact that a lot of both the cowboy and native American characters looked very similar.....hmmm! Maybe watch it with sub-titles!
However the story was unusual for a western, good plot, and the main characters well portrayed. Worth a watch.
