I get that believability thing with his male costars. I saw it very early in previews last year, and I can see how their relationship would develop over the past year. It was already becoming pretty well-established when I saw it.
Personally I thought his dancing was stellar. His acting, okay. Singing voice….good enough. Not the best acting or voice I've heard, but definitely good enough not to detract from the show. He held his own in a beautiful show and did his part. And his dancing was very good.
I think that if I hadn't seen it, I'd want to see him…. just to see the original player. Especially considering the Tony nod. I'm sure his acting and singing is probably even sharper now than it was when I saw him. I'm sure as he's grown into the role.
When I saw him, amazing dancing! The other elements of his performance. Good. But not something I walked out thinking, 'Great acting….great singing!'
He was good though, and I enjoyed his performance.
