I was in SF (for a Kylie Minogue concert, of course) when this was running in the city, so saw it probably a week before it was frozen. It was LONG. But I really liked it, and thought it had potential despite a set that didn't really work.
There's a LONG thread somewhere here with comments from myself and others. I'll try to look for it. I thought the music was great, as were most of the cast (Judy Kaye as Madrigal especially -- when I had bought tickets I was disappointed that Buckley was no longer in it, but I think Kaye was ultimately a better fit. Pamela Myers was her understudy and played various roles when I saw it which was thrilling for someone like me who never gets to NYC.)
Betsy Wolfe as Mary Ann was note perfect and sang the show's best song, Paper Faces. The problems with the show were, as expected, stitching all the stories together (they used stories from the first two books.) That said, I stand by my statement in the earlier thread that the show has promise and I listen to my "recording" quite often.
