I saw it Wednesday night, and thought she was terrific!
The differences, to my eye, were that she doesn't play it quite as "dumb blonde" as Cheno did - and I got much more of a sense of her wanting to feed her own ambition, which is a very subtle change for the character, but one which I think enhances the story. She was playful and sweet, but with a not-to-be-messed-with core. I like the take.
The only distraction for me was that her voice and Idina's don't blend the same way Cheno and Idina's voices did - which I'm so used to hearing, BUT, I'm sure the blend and timing will 'improve' with time. (After all, they didn't have alot of time to rehearse together). The chemistry between them is great - if you had never seen Cheno you wouldn't miss anything.
George Hearn was a little stiff/unsure on Wednesday night. I adore him, but have to be honest and say that I loved the way Sean McCort played the Wizard when he was on. Looking back, Joel Grey did a good job with a very underdeveloped role.
Joey McIntyre is cute - and has a decent voice, but I really enjoyed Norbert's take on the character. I didn't get the sense, in Act I, that Joey's Fiyero was falling for/taken with Elphaba as much as being unsure of her...
And, just to round it out - I actually like Randy Harrison as Boq. He brings a nice energy to the role.
So - I'll be interested to hear what the rest of you think as you see it...
