Nope, I wouldn't say that at all. Many of the minor characters in Wicked turn up in the first Oz book which I didn't catch until I was rereading The Wonderful Wizard of Oz. Also the shoes are silver, not ruby. I don't know. I see how the physical look of the Witch of the West was used from the movie as opposed to the book but I found it very true to the Baum stories, especially the political spin that Maguire took. It was neat to see that political satyre that Baum was playing with be taken a step further and a step darker.
