Buck is a documentary about Buck Brannaman, a modern-day cowboy who teaches people how to train their horses. He's a soft-spoken man who had a horrible childhood that he thankfully escaped to become an incredibly decent man. (Plus, he was the inspiration for the book The Horse Whisperer and was a consultant on the film adaptation.) Buck is modest -- maybe to a fault -- but it's a nicely gentle little film. My full review is up at Yahoo.
