Love the movie. Love the book.
When I got my first teaching job, I was also assigned to be the fall play director. I chose to do Wizard of Oz. It was a non-musical. One teacher wouldn't stop her bitching about how the Wizard of Oz is only a musical and how I shouldn't be doing that play. I continually pointed out that Oz was adapted into several stage plays before it was adapted into a musical, but she refused to listen. Then again, she had an axe to grind with me because, apparently, her daughter also applied for the job that I received.
Among the other differences, the novel of Wicked plays more into the Oz book series whereas the musical plays more into the movie.

I must say, I did not, for the most part, enjoy the novel Wicked. (My sister-in-law and niece, both huge Oz fans, tell me I really need to see the musical, though.)
The book and musical are quite different. Like the film, all three are unique interpretations of the source material. The musical has LOTS of playful nods to the film and easter eggs abound.
