Another movie that showed both sides fairly:

"Son of the Morning Star" (a biography of George Custer)

Because it showed both sides fairly, it was by far the best film ever about the Custer episode and the Battle of the Little Big Horn. You could see how his own recklessness led him eventually to disaster, and you could see his various character flaws...as well as his strengths, but the whole movie was not a setup just to make you detest George Armstrong Custer...which is what most of them have been since the 60's.

Before the 60's, of course, they made movies in which history was grossly rewritten to totally whitewash Custer and in which Indians served only as multiple moving targets on a firing range. The one with Errol Flynn was a classic among those...and it was good rousing entertainment, unquestionably, like all the films Flynn did...but it was absolute tripe as history.
