It's silly how much hate has been spewed in this thread because an audience member wants to see a Tony Award-winning actor in the role they won their Tony. Yes, Jim is great. He's not Tony great, and I can understand the disappointment when someone is unexpectedly out. Unfortunately, that's how theatre works.
Gabby is great, but she's not at Lucas' level in this role. That's more a testament to how long Sydney was in the role and developing her performance. I'm sure Gabby will get there; she was already getting close when I saw her a month or so back.
