As a matter of fact, that is what I like most about Wicked, both the novel and the movie.
It's very interesting if you consider that life is the same way. Life is viewed through our own set of eyes and what is reality to other people might not be our reality.
And interestingly enough, that is a prevalent theme in the stage show as well..that not only are there two ways of seeing the "same" story, but also that people are misrepresented..as the Wizard says I believe..that is history is written by the winners.
Jim Caruso: You know, you are doing Wicked.
Stephanie J Block: I am!
Jim: Is anyone coming to that old thing?
