Here's another movie that I recommend in case you haven't seen it yet.
I love the idea of frontier exploration and the valiant effort it took to communicate with the native American Indians.
The story's good and the way the movie comments on life, finding happiness, and what things are really important - such as Dunbar's conflict with his duty and with what he decides is morally right is really well done.
The action in the film is well done with Indian vs Indian and soldiers vs Indians, not to mention a great opening that takes place during the Civil War with Yankees vs. Rebels. It's all good.
The music here is great, too. I love epic films.
