Conclusion: It's a bad movie based on a potentially nice story.
I don't know how some directors can destroy the story by making very bad movies. Hollywood has not made good movies about native Americans for a long time.
"In 1892, a legendary Army captain reluctantly agrees to escort a Cheyenne chief and his family through dangerous territory." IMDB
There are big questions about this film:
What is the role of Cheyenne chief in this movie? He is always silent and we do not see the character of an Indian chief. He has a few words in the entire movie and they are just cliche.
What is the role of Rosamund Pike? She decides to company captain and his group but it is clear why.
Christian Bale is the star of this move. I like his character and he shows that he is able to play hard roles.
The end of the movie is ridiculous and does not make any sense!
I wish we could see another nice movie like "Dances with Wolves "
Thanks buddy!
