So I was hanging around to see if anyone brought this up, it is a primarily Black Western . I watched it on a flight recently and enjoyed it. Similar in style to some Spaghetti Westerns, written and directed by an English musician, (Musician Seal's brother) who is a big fan of the Western Genre (really think most Europeans like them better than the average American, not that any of us would fall in the Average category).
It had some good gun fights. Delroy Lindo looked like Bass Reeves, and I have always enjoyed him. Overall, an enjoyable western.
Big stylistic mistake was a gundown on the train and all of a sudden all these spent cases are falling on the floor. That would make sense in a modern film with a semi-auto, but does not really make sense in a western and 6-guns. I wrote that off as music video styling mistake.
All I can say is I hope it brings in more fans and shooters.
