I saw Wicked, it was actually really good. There was a hidden twist for each character compared to The Wizard of Oz. The only one I forget is for the Tin Man.
I know which characters I want to be what, kind of based on "compatibility" and attitude.
Although I kind of mistook Ash for Luffy on One Piece(anime - Luffy is an idiot - like the Scarecrow without a brain)
