Wicked is the story of Elphaba and “explains” why Elphaba became “wicked.” Maguire raises the question what does it mean to be “wicked.” In some sense it is a prequel, describing Oz and creating a fully developed story line that integrates all the characters from The Wizard of Oz, and then some. It is an allegory, and studies the meaning of good and evil, connecting this tale with real historical concerns. Highly recommend.
