The Only Good Indian trailer

Comment:  The story appears to go like this:

Native boy gets lassoed and taken to boarding school. Is forced to work but not to cut his hair. Runs away to return home. Is pursued by Wes Studi the bounty hunter.

But when a white gunslinger tries to kill the boy, Studi turns and defends him. Gets in touch with his Native roots, which he's ignored. Gunslinger chases Studi and boy, leading to a final showdown between the two men. Someone dies.

Offhand, I'd say The Only Good Indian looks good but not great. We'll see how it plays eventually.
