I just got back from this evening's performance, and like the previous poster, I enjoyed the show overall. Bradley Dean was very good, and, to me, the first act was mostly excellent. But in the second act, there were too many slow numbers for my taste, and they mostly seemed to cover the same ground -- pretty but somewhat cliched love ballads.
Also, toward the end of Act One, a bunch of characters got on a raised platform that was supposed to be a train, and then they all just sat there motionless. After a few moments, a new scene started in front of the "train," and I was thinking, "This is a really original, out of the ordinary staging -- there's a ghost train filled with frozen images of soldiers right in the middle of Dr. Zhivago's house."
But, then a voice came over the loudspeaker saying the performance would have to be stopped. And after a bit, the actors were asked by the loudspeaker voice to leave the "train." Finally, they got rid of the raised platform (I believe it sank beneath the stage), and the scene with Zhivago started over.
