Underrated
Yes, at times it has a certain undesired B/indie feel to it (only because of some weak moments from some of the actors), but all-in-all this is a very well handled gritty western.
Not because of authenticity or realism in itself, but because some of us want this from a western. Caricatures, strong personalities, brutality and Tarantinoesque dialogues, monologues and long scenes all wrapped in a seemingly simple story. It's dirty and unforgiving.
Also - the filming/photography, locations, effects and makeup is all very well done. Breaks my heart it receives the all-damning 5.x on IMDB. Personally, I rate it 8/10. E: And one of the best movies I've seen so far in 2016.
