just started reading wicked, I always wanted to see the play but never did. It is really good so far.
The play and the book are different in important ways. The book is much darker. Both are about the time before The Wizard of Oz takes place.
The musical is more fun (you know, like a musical!!) with a different ending - completely different. If you read the notes on the soundtrack, the writer was completely on-board with the changes as he recognized the need for certain elements in a musical play.
Personally, I prefered the musical and would recommend it to people who like that sort of thing.
