Bury My Heart at Wounded Knee

Does the film successfully capture the temper of the times, the ideology of the age it alleges to portray? How do you know?

I actually just watched this film in prepartion for a midterm.  It really is only about the Sioux and focuses on Red Cloud and Sitting Bull.  Crazy Horse is mentioned multiple times, and they also include Charles Eastman - who is never even mentioned in the book.

The movie is good to catch a feel of what the Natives went through once they got back to the reservation, but it's only very very loosely based on the book.  

The movie also portrays many white men as sympathetic or interested in negotiating, which wasn't quite true.  Dawes (Aidan Quinn) of the Dawes Act is in there a lot, and he shows up when he's wanting to negotiate some new treaty.

Long story short, there's a lot of history in it that's correct.  But it only really focuses on one Native group and a few of the subsects within it, which is nothing like the book.
