I've only seen Wicked once, so i've got to stick with Kristin, she originated the role and created Galinda from almost scratch. Everyone else is just stepping into a bodysuit so to speak.
By the way. Is it just me? Or is everyone tired of the relentless bickering back and forth over the same pointless topic between the same people?
"Why can't you just teach us history, instead of always harping on the past"~ Galinda
"Who takes shoes from a dead person?!" ~ Elphaba
"And what have you been doing-other than riding around on that filthy old thing?"~Glinda
"Well, we can't all come and go by bubble."~Elphaba
