The Wizard of Oz

Dorothy, the Scarecrow, the Tinman and the Cowardly Lion are all weakened aspects of a fractured self, hoping to find the answer in the Wizard, aka the Perfect, Unified Self, which hovers in infant memory.

The trip is going back to that Perfect, Unified Self, but when the fractured self arrives there is nothing there to make things good - the Unified Self was just another pretender, a projection of the desires of the weakened aspects, and the real controller, if there is one, is at least another level up, where our travelers can't go.

Alone and broken, but does it matter? Not if the belief system that creates such perceptions is overcome, the one that sets up the idea of there being a Perfect, Unified Self, the one that labels the disparate parts of the self and then insists on these identities.

At the end of the movie the main character forgives and forgets, and any idea of perfection, unity or the past is lost - it was all a dream.
