I mean, if we are looking for a multifaceted portrayal of indigenous characters with depth, maybe (just maybe) we should be looking at Reservation Dogs and not Yellowstone?
Not to put to fine a point on it, but one is about indigenous characters, written and directed by indigenous people, and starring indigenous people, and the other is about ... well, let's just say that it is starring Kevin Costner, Klly Reilly, and Cole Hausner, and written by Taylor Sheridan.
(That's not to say that Yellowstone doesn't do a creditable job in its portrayal, but I wouldn't exactly hold it up as the gold standard.)
