Bone Tomahawk 2015 (film review)

 "Four men set out in the Wild West to rescue a group of captives from cannibalistic cave dwellers." IMDb

 Staring Kurt Russell and Patrick Wilson (among others) the film is set during the "wild west" days. 
 This is a western with a difference, while it has cowboys and Indians it's not the usual sort of Indians, this is a small tribe of sort of cannibal Indians.  The plot revolves around the small group of Indians capturing the wife of one of the townsfolk and the subsequent chase and attempted rescue (don't want to give too much away)
Now I'm not really a fan of westerns, but I found this surprisingly watchable, it's different enough not to be boring.

Waynes rating 7/10 worth a watch
