I'm glad you and the Mrs. enjoyed the show Mr. Roxy. I saw it a couple of weeks ago with friends and I'm sorry to say I saw the same show as the critics. I, like one of my friends, didn't enjoy it at all; yet the third friend with us thought it was a the best show he'd seen in years. It seems to me there's a bit of a love/hate relationship going on with this show. It did received the obligatory standing ovation at the end; not by all, but those who did stand were very enthusiastic and vocal in their show of appreciation.
Barbour has a booming voice yes, but I've never cared much for his acting style. I found the music forgetable, the lyrics regretable, and the sets and costuming - no big deal. I enjoyed the lighting however.
Admittedly, I found the second act more tolerable than the first but in the end I didn't care much for the show as a whole. I wish all involved the best of luck, but I think it will be a struggle to keep the show open for any length of time; especially with the economy being what it is and theatre patrons having to pick and choose the shows they can afford to see. AToTC, in my opinion, will have the cards stacked heavily against it once the some of the other supposed 'big' musicals come in.
Still, it's part of the variety of Broadway and why NYC is the theatre capitol of the world (IMO). There's a bit of something for everyone.
