Not familiar with Redmond's work, but her clips are rough. I agree with you, somethingwicked, that it seems to have something to do with the size of the stage. She seems to be struggling to fill up the space and that's a requirement for Tracy. Tracy's energy should fill the entire theatre.
I used to be so pissed that Winokur won the Tony over Bernadette Peters (being a huge fan of Peters and her performance on the GYPSY album) but over the years, the more I listen to Winokur's performance, the more I realize what a unique turn it was and I'm so happy she was recognized. I feel like there's actors out there that I can see being good Ednas, but I can't think of a single person who could match Winokur's Tracy.
