Included actual footage of buffaloes being shot as part of the annual herd culling at Custer State Park. That made for a pretty gritty movie. Taylor was truly insanely despicable as Gilson. Granger was good as a guy who had done enough killing and was tired of it. It was a fine idea, but I felt that somewhere along toward the end, it jumped the shark. The end just didn't feel realistic, especially the part about Gilson freezing to death.
