If you’ve seen one revisionist western, you’ve seen them all. It’s always the same old thing. The heroes are actually unheroic. That’s it. That’s the whole point, and we already knew that. To make matters worse, Buffalo Bill and the Indians, or Sitting Bull’s History Lesson is directed by Robert Altman, who keeps running his MASH style of movie making into the ground: people talking over one another, lots of silliness, quirky characters. It worked great in MASH, but it won’t make silk out of a cow’s ear. This movie ranges from boring to irritating.
