Completely agree with every word Dusoleilcanwhistle said.
Saw this last night and left completely bowled over. It truly felt like I was seeing the show for the very first time.
It is a much more grounded and bare bones production. No real flashy lighting, a mostly utilitarian set, but performances that feel so lived in and natural. With direction from Michael Longhurst that really seems to take you into Diana's mind in often harrowing ways.
Caissie Levy is giving a career-defining performance. Vocally, she has never been better, and it was a breath of fresh air to hear the score sung this beautifully without sacrificing any of the acting. I really loved Alice Ripley in the role, but Caissie's performance feels more nuanced in many ways. She is a Diana who is really trying her best to cover up what is happening to her, and the cracks begin to show until she can no longer hide it. She has really become such an incredible actress over the years. I've always loved her voice, but since Caroline or Change it seems like she just keeps getting better and better, and this performance is truly spectacular.
Jamie Parker is a Dan you instantly understand, you love, and more than anything, you feel for him. This is the first time it ever really seemed like Dan and Diana actually love each other. His breakdown at the end of the show is devastating, and while he may not vocally hold a candle to J. Robert Spencer, Brian d'Arcy James, or Jason Danieley, he acts the absolute crap out of this material.
For me, Jack Wolfe is sort of the unsung hero of this production. A performance that is definitely helped by the direction taking a character that I didn't think was much more than a role for a hot guy with a beautiful voice and turning it into something I really don't even know I can put into words. At times haunting and sad, at others terrifying and impish, he is doing things with this role I truly did not think were possible.
Eleanor Worthington-Cox is a perfect Natalie. Vocally incredible. And it was heartbreaking to see a Natalie who from the very start feels like she herself is on the brink of falling apart. She's such a younger actress but she approaches the role with a level of fearlessness I haven't seen from some actors twice her age.
Desperately hoping this transfers for a proper West End run, and hopefully a New York stage sometime in the future. If nothing else, this cast needs to be preserved on a recording.
