If you’ve not yet read it, seen it, or heard people talk about it, Wicked is what happens when somebody takes a well-known story (The Wizard of Oz) with a nasty villain (The Wicked Witch of the West), and retells the story from the villain’s point of view. In the process the villain ends up the sympathetic character. She wasn’t born wicked, she was just born different. It’s what the rest of the world does to her that makes her the way she ends up.
Which Shakespeare play would be most ripe for this treatment? Which villain could you make the star of his (or her) own show, and in the process make her (or him) come out looking like the sympathetic character?
