What are your themes?

Inspired by the many pre-christmas topics asking questions to the members of Gamasutra, I decided to post mine as well about a subject that I feel concerned about: themes.

Every writer, especially, script writers, have his own themes. Those ideas that are implicitly inside every of his stories. Sometimes they don't even know it. But it's still there.

Great movie directors have their own too. You can see them in their movies. Christopher Nolan talks about lies and manipulation, Stanley Kubrick talks about madness, Among other things.

If you don't know your themes yet, this is something you will have to figure out. Unless you don't want to write stories. The more specific your theme is, the better. That makes your stories more uniques than others. Everyone can talk about love and death. The question is: which aspect of love or aspect of death you want to talk about?

So my question to writers is: What are your themes?

Mine are:

-Crossing the line between good and evil. espicially in that very sence.

- The Fourth Wall
