Oz vs. Narnia Worldview

In The Lion, Witch and the Wardrobe, it portrays the Christian worldview. Aslan is symbolic of Jesus, the kids are the "sons and daughters of Adam and Eve", and the witch is Satan. This is all stuff we should already know. In the movie, the kids go through a closet into a new world. The world in which they enter has the same type of conflict as the world today. It has a constant battle between good and evil, in which good will ultimately win. The reality is that these kids have the chance to make mistakes or follow Aslan (or God). They sin, and need a Savior.
In the Wizard of Oz, the main chunk of the movie takes place in Dorothy's dream, so it obviously isn't reality. because she's asleep. But basically the characters have been living in a way thinking that they cannot help themselves, but need someone higher in power to help them. In the end, they realize that they create their own happiness by looking into themselves for the power. They can fix themselves and make their circumstance better on their own.
