I saw it last night. The problem is CLEARLY the book.
The score is gorgeous, no question. It's beautifully sung by an excellent cast. The production itself is solid, if not super-impressive. The direction was good with the small exception that, from where I was sitting in the fourth row on the side I couldn't see several scenes. For example (and I forget which song it was) the kitchen set was on, and stuff was happening behind it that no one on my side of the theater in at least the first seven or eight rows could see.
SPOILERS
The book is clearly the problem. My wife claims it's because I'm male, but I just didn't buy that a four day romance would have effects on this guy who's made a life of running around the world basically at will. The end felt so fake to me. I feel extending the time of their romance - make it two weeks or something - would have led to the ending being much more believable. Other problems - there is LITERALLY nothing wrong with Robert. He's a perfect guy. Yeah, he has an ex-wife, but we never really find out why they split (unless I missed that). But there's nothing WRONG with him. I also think having the characters as young as O'Hara and Pasquale are detracts from the story. Yes, the score is incredible (and I want it to win the Tony) and you need people like this to sing it, but again the end of the story doesn't work for me because it's hard to believe that someone as young as Robert, going back out into the world, simply never found ANY other loves -- after all of four days with Francesca. I don't know, it just didn't ring true for me, which kind of ruined the ending for me.
When I was in college studying drama, one of the key things my musical theater professor said repeatedly was a bad book can kill an otherwise great show. I think this is clearly evidence of that.
