I have to agree that the 'hubris' factor didn't do YF any good - even from the other side of the pond, the most notable thing about the show in its preview period was those ridiculous $450 seats. People expect the greatest show on earth for that price (even if only a fraction of the tickets were that expensive).
I enjoyed it and I thought the cast did a great job. It is a funny show in its own right, even if it's not up there with The Producers. The audience response was very enthusiastic and there seemed to be a virtually full house when I went (in contrast to Xanadu which I saw in a half-full auditorium on a Saturday night in a theatre which must have been only a fraction of the size of the Hilton).
I can't really comment on the subsequent marketing, other than to say it appears that the controversy about the premium seats was a massive own goal which didn't do the show any favours at all. Too easy for people to say 'It wasn't worth $X', when they probably wouldn't even mention the ticket price for other shows.
Seen some shows in my time....
