I have to agree. The show's pleasures were always tied to the concept of sci-fi bursting forth in two small spaces at the same time: a flower shop, and a tiny theater. The conceit was baked into the humble origins: a B movie turned into a small-scale show. When everything gets bigger, the fragility is exposed. No, the show didn't fall apart, and the score is perfection. But it had an almost cabaret space feel; in a B'way house, it felt pushed, trying to hard.
House size is not a small issue in how material lands (talk to people who are sitting upstairs at "The Sound Inside." So many of my friends in less perfect seats felt the show didn't project).
