I read the book and loved the book but the musical, in my opinion, really assassinated the characters' personalities. Boq did have a crush on Glinda, but she returned the affection and then he lived happily with a family of his own. Nessa was more or less a religious zealot and didn't have feelings for Boq. Fiyero was younger than the others, was already married and never had any feelings for anyone until he met Elphaba years later quite by accident. There was also no grand scheme by the wizard to make the world think Elphaba was wicked. It kind of just happened through rumours and say-so. And as for the scarecrow thing, Elphaba wanted more than anything for the scarecrow to be Fiyero and after years alone in Fiyero's castle with her nanny, monkeys and possible son, she was more than heartbroken to find out that the scarecrow was just a scarecrow.
And as far as the musical goes, "life is aimless for the brainless"? I pretty much figured out by then while trying to dodge the falling anvils that Fiyero would be the scarecrow at the end of the show.
I saw the show for 3 reasons: Idina, Kristin and Joel. I was impressed with them, but who wouldn't be? And I'm glad for any show that attracts new people to theatre. I just wish the show was as good as the book.
