Made in 1954, this film does attempt to tell the story of the Black Hills from the point of view of the Sioux. It just does an absolutely terrible job of it. Simply telling the story historically accurately would have been a far better account, and that information was available in 1954 (at least enough of it).
The good parts?
The impact of corrupt Indian agents, and prospectors going into the Black Hills. Showing Sitting Bull in a positive light.
The bad parts?
Pretty much everything else - the entire role of the main protagonist, the portrayal of Custer (although it does get it right that he was a prima-donna and he disobeyed orders), the Court-Martial (as demonstrated with the Court Martial of Captain Reno), and the Battle of the Greasy Grass.
