The Worldview of The Wizard of Oz

The worldview of the Wizard of Oz has much to with postmodernism. Atleast, that's what i believe... Every main character has something close to them, the courage for the lion, the heart for the tinman, home for dorthy and so one. The thing is, all of the main characters are after the 'Wizard', or 'God'. And 'God' means something different to each of them. However, like postmodernism, 'God' turns out to be nothing, a fake, a shame, not real. And after that's discovered, the whole idea of the journey turns out to be a dream. The 'unrealality', if that's a work, of this makes the Wizard of Oz closest to the postmodern view.
