Don't see this film if you don't like sarcasm! It's not as much about the history behind Buffalo Bill and his Wild West show as it is about making fun of the racist attitudes present in many Western films. There are also some good laughs available when Annie Oakley shoots and her "target" flinches with anxiety.
The satire also explores the way Bill runs his show, or the way any CEO might run a company, and whether truth or entertainment is more important to the crowd. The truth Sitting Bull wishes to bring to the people is much less important to Bill than are his ticket sales. The juxtaposition of Sitting Bull's meekness and the way Bill portrays him in the show as a murderous, ruthless warrior is really brilliant.
