I saw it in the original run at the St James and was one of the only two times I've witnessed an English audience give and standing ovation. I, however, did not stand. I was clearly in the minority who thought the actors and director didn't get the tone of the piece or the humor correctly. I found Jenna Russell to be good, but she and that part both have potential to be stand-outs. Richard Fleeshman looked gorgeous, but sounded pretty bad the day I saw him and was so so so bland, not at all winning, charming or funny.
But like I said, the audience went crazy at the end and it got wonderful reviews. This production wasn't for me.
