I love Bernadette, so let's start there. But her Sally was either directed poorly or the director let her go with her choices, which were completely wrong for the character, IMO. If Sally is crazy and sad and depressed and delusional from word one, you have no show, period. Anyone who thinks otherwise clearly does not understand Follies or the way in which it's written. It's why everyone who was lucky enough to see Dorothy Collins knows there will never be a finer performance of Sally, acting-wise or singing-wise. She was heartbreaking BECAUSE you discovered her deal as the show went on, not at her entrance. That's what makes it work, discovering her issues as the play goes along. That's called, in the parlance of now, an arc - there was no arc to Bernadette - you got it all right from her entrance and it killed any chance for her. A good director would have stopped it. But the director of the revival is anything but. And yes, John McMartin was the best Ben there will ever be. In fact, the entire original company is the best there will ever be - many reasons for that, starting with brilliant casting but, more importantly, Mr. Prince and Mr. Bennett. The endless revisions to this show are all horrible - adding an intermission is reprehensible and horrible and I hope these Brits have the courage of their convictions and do it the way it's written - no revisions and no intermission.
Why they would announce the filming of a production that no one has seen one second of is another enigma for another day.
