I love every aspect of this movie, especially Coop's performance. This is (in my opinion) his greatest performance because he was the perfect representative of America's veteran's coming home from a major war and stating clearly that he is not proud of what he did in his service to his country. In the film (as well as the real Sergeant York) he is offered several thousands of dollars (possibly millions) and he refuses it for those reasons stated above. This is my idea of a true hero and what better role model to have than Gary Cooper.
