I saw her yesterday at the matinee in Houston. She was fine, but I was definitely not blown away and, to me, Wicked is the kind of show that really needs an exceptional performance in that role to carry the show.
I have to admit I was in a foul mood as soon as I saw the sign up that both Elphaba and Glinda would have understudies on. I realize people get sick or injured, but it sure seemed like they were off because it was the last day in town. If the producers want to schedule off days for the stars, I understand, but they should build it into the schedule and adjust ticket prices accordingly the same way they charge less for Tuesday-Thursday nights.
Yes, I know understudies have a hard job, and they're gaining experience and learning to be stars. I also know they are sometimes just as good as the regular, but Wicked is not a show where that is likely to happen.
Pass it on - Take a kid to a show.
