I think that this movie achieves its aim in demonstrating to the audience the tragic wastefulness of nineteenth centuries bison hunting. It doesn't really touch on the racialized element in the destruction of bison, in that it was in part based on the belief that "one less buffalo meant one less Native American." But it does aptly portray the greed. It also portrays the monotony of hunting bison, which makes for a movie that is sometimes downright boring and repetitive. There is a lot of attention paid to accurate historical details and Nicholas Cage is excellent as the brooding, disturbed, obsessive Miller. Xander Berkeley also puts in a noteworthy performance. Overall, a powerful message wrapped in a somber and kinda dull film in the "we lost ourselves in the wilderness" genre. Worth the watch.
