I saw it December 10th, and plan to see it again by the end of this weekend. In December, it was a show that was obviously still trying to find it's core. The story, while easy to follow (for someone who didn't read the books), was all over the place character wise. I was never sure of who I was supposed to be "rooting" for.
The sets, as Lizzie mentioned above, were not great. I found myself distracted by the lack of them. The Projections of the "thoughts of the victims" as Lestat took them did not bother me as much as it did others. I could see what the show was trying to say, but it needs clearer images. Too much time was spent trying to figure out what I was looking at, at that detracts attention from the actors in the scene.
The acting was good. All leads were enjoyable and had good singing ability. I particulary enjoyed hearing Carmello singing live. The songs were just ok. The first act songs all sounded alike to me, with a lot of "dialogue as singing" going on. Crimson Kiss is the only song I actually liked, and I can't remember any of the act two songs other than Sail Away. The only reason I remember this one is because Panero was singing it while standing on something that looked to me to be a huge ship mast on a tiny island. My binoculars told me it was actually supposed to be a ship's mast with waves cresting underneath it. It didn't work and ended up looking ridiculous.
There is definitely a chance for this show to be good. It just needs more time and work. As an audience member, I wanted to see a more cohesive storyline, sets instead of bare stage and ships mast or columns, and songs that matched the characters emotions a little better. Can they do it? I have no idea, but after seeing shows like Titanic make it to Broadway, I'm not going to guess on Lestat's fate.
I suppose I didn't have as much trouble as other posters because I went in realizing I was going to be watching a work in progress. That's why I plan to see it this weekend as well. I want to see what the end result of the out of town tryout looks like before writing the production off as a failure.
