I'm in the minority here, but I think Wicked at the Gershwin is a completely different experience than seeing the show on tour. In fact, I never actually "got" the hype surrounding Wicked until I saw it at the Gershwin. The built out scenic design that extends into the house is a wonder to behold. I saw the second national tour about a year ago and found it overall to be rather weak.
