My daughter, wife and I watched Bone Tomahawk this past weekend. It was availalbe on-demand from our cable service. It is too graphic to be a family movie, which you can probably tell from the trailer and the rating. My (adult) daughter and I watched it entirely, but my favorite wife, Mrs. Red, got up from the couch as one scene near the end of the movie was too graphic for her taste.
I wouldn't call it a great movie, but I did like it...especially since there has been such a dry spell on western movies.
