I was also at the Wednesday evening performace, and am glad to hear today (Thursday) of changes.
I also had problems with Armand being weak in the first Act. Interesting to note that they are taking the character in a "new direction".
I would suggest that they explain how down and out Lestat is and that he buried himself underground right before Marius makes his entrance. Not ever reading the books, this had to be explained to me later. With the set being "bricks" over top of him with he being in a "black hole", I though he was under a bridge. Once it was explained, it very much made sense.
I also agree with other posts that the song aboard the ship could be done away with, or changed. Lestat is supposed to still be very weak at this point. I am told that in the books, he was down to eating rats, etc. This is too strong of a song if he is to be in that condition....and is weak right after arriving back in Paris.
The show has great potential with some work. For me, the first Act flows well, with the second being choppy.
