Caught this tonight and was utterly charmed. I have never seen a production before, but I had a grin on my face for much of the 2 1/2 hours. I won't recount the plot, as others have already, just add my take.
The cast is quite good and with apologies to Ms. Murin, I don't know what's going on in the cafe scene and Peter Bartlett. The scene stops the show and not in a good way. Mr. Bartlett, whom I have enjoyed, in the past, is so out of place, that he makes a poorly directed scene, even worse. The scene drags and almost makes everything, enjoyable, that came before, in act one, vanish. I enjoyed Ms. Krakowski, but I'm not convinced she has finished developing her character. She's still lovely to watch, though. Zachary Levi is utterly charming. I have never seen him before, although I knew of him. He seemed so invested that he didn't want to be anywhere else, but on that stage. I'm a fan.
I only knew a few tunes from this show, but really loved the whole score and found myself not just listening to the lyrics, but the music, as well, which doesn't always happen. I could not understand most of the words 'Twelve Days to Christmas'. Maybe, it was where I was sitting on the far side orchestra.
The staging is ingenious and almost too perfect for 1934, but I rather enjoyed the cleverness.
The Roundabout orchestra sounded nice, but a little small. I have come to expect that from Roundabout.
Overall, I really enjoyed the show, save my quibbles. By the conclusion, I had, pretty much let my quibbles go and was won over for a mostly fast-paced 2.5 hours
