I don't think anything in this revival (save for maybe Mary Testa and the choreography) can be described as "amazing." Even the good things were simply brought down by the awfulness surrounding it. Having said that, I do think Kate Jennings Grant was wonderful, I don't think she was boring at all, if anything she managed to inject life to misdirected, misacted, and utterly bad scenes. She had so much personality, and her Sarah Brown was quite passionate. It was at the very least an interesting take on the role that worked, sadly the performance couldn't realize its full potential since the direction was so terrible and the rest of the principals weren't up to par. I think she was stronger than say Josefina Scaglione (whose performance also suffered from being in a misdirected production).
Craig Bierko was okay, not great, not wonderful, but he was fun to watch.
Having said that, Lauren Graham's Adelaide should never be recorded for posterity.
