I recently attended a production of Wicked at Shea's Performing Arts Center (in Buffalo, NY), and can't remember ever enjoying a musical so much. Everything seemed to work -- the music, the cast, the high-end theatrics, and, of course, the story and its rich link to The Wizard of Oz source material.
I was particularly impressed with Carmen Cusack, who plays Elphaba (the Wicked Witch of the West).
After the show ended, I couldn't stop thinking about it and kept coming back to the feeling that this was so much better than the second Star Wars trilogy and a far superior retelling of a story from the point of view of one of its villains. Perhaps Wicked revealed just how much you can do when you really shift the point of view and tease out the possibilities. Or maybe Elphaba is just more fun than Darth Vader. And more green.
