You can't tell any kind of a story without having some kind of a theme, something to say between the lines.

When the news wants to tell you something is important, they put dramatic theme music behind it. They scare you into watching the story.

Any story that Billy Wilder told, you can tell in a Western.

If you can tell a story well, you can move people to do something.

Never preach a sermon without a text from the Bible, a text containing the theme which you can elaborate. The text is the best proof in support of your argument. A sermon without a text is an argument without a proof.

With Westerns you have the landscape is important, and it's empty, and only you populate it. When you populate it, you can tell any kind story that Shakespeare told, you can tell in a Western.
