I'm sorry but I have to add some Sutton love to this thread! I, for one, thought she was brilliant (not at all over-rated). Beth Leavel is a star, through and through. I really enjoyed seeing this show, so I do think you should see it on Broadway, no matter who is in the cast :)
I don't think you'll walk away disappointed.
"Now she wants to know WHY, if I'm so fabulous, I would WANT to take care of her child.....I answer with as much filigree and insouciance as I can muster, trying to slightly cock my head like Snow White listening to the animals. She, in turn, is aiming for more of a Diane-Sawyer-pose, looking for answers which will confirm that I am not there to steal her husband, jewelry, friends, or child. In that order."
