There are great films that depict the horrors of war and honor those who sacrifice themselves as part of it. Saving Private Ryan and Fury come to mind. There are many as well about civilians who sacrifice money, career, and even lives to promote the progress of a cause or idea greater than themselves. Sacrifice is a noble thing. Of the one who sacrifices his life, the Bible says there is no greater love.
High Noon does not explain itself nor its hero. One suspects that what Tony Soprano really identified with in Will Kane was his reticence. In today’s political landscape, Kane’s insistence on taking up his gun even after he had officially resigned his position might well be questioned. Neither his wife’s arguments for pacifism nor the town’s pleas for pragmatism are clearly and effectively rebutted. Kane represents an emotional rather than intellectual (or political) argument. The way things are is stipulated, not explained. A man has to do what a man has to do. What that thing is that he must do can only be understood, not explained.
