Kurt Russell's appearance and character in Bone Tomahawk is not dissimilar to his role in Tarantino's recent Western The Hateful Eight, and he almost carries the whole film through its misfiring and clumsy plot.
The film starts with real panache - an offbeat Western with a touch of evil in them thar hills - but it soon resorts to an amateur, paint-by-numbers script, which is such a shame. What kept me interested until its gory end was something approaching to the feeing I got from The Texas Chain Saw Massacre in the mid 70's. The plot and twists are unlikely, but then again just about plausible, so you're in state of suspended, uneasy fear for long stretches.
The film gets halfway to where I think it was aiming. It could have been a brilliant cult classic with just a bit of judicious editing.
