It was awesome! I really anjoyed it when I went to see it with my school. I wish tickets weren't so hard to find, I'd like to see it again. I have the soundtrack though!
Its really more detailed around Elphaba (Wicked Whitch of the West) and Galinda, but they do add some of the parts about Dorothy in there and you find out more of the background info of The Wizard of Oz. Its very interesting, and lots of funny moments.
