For me, "Bone Tomahawk" is a blend of two distinct styles. The first half of the movie plays like a traditional Western. The one which it reminded me of most, in terms of its storyline, was the John Ford classic, "The Searchers" (1956), albeit with a more modern slant. For its final half, however, it turns into something completely different, a blood and guts splatterfest that Tarantino would have been proud of.
As someone who appreciates both Westerns and horror flicks, I really enjoyed it but it's not a film for the fainthearted.
I'm really liking the Steelbook artwork and hope that it doesn't change. Normally, with Zavvi, I'd wait for a price drop but this is one title that I'm tempted to order from day one, provided there's a valid discount code available.
