Oz god

I think that the Wizard of Oz is a form of Post Modern worldview because the characters in the story create their own form of god, the wizard. I have heard many people today say that it is of a christian worldview. Honestly i have not seen the whole movie. I have just seen the part where the tornado takes place and the movie turns colored. It is hard for me to give an in depth analysis of this but from what Josh says, he has convinced me that it is of a Cosmic Humanism worldview.
