Saw the show at Union Square and in London (where, with a different director, it was diffuse, flabby, and humorless). I enjoyed much of it in NY, but it's a very uneven/inconsistent show, and the London production showed that much of what I enjoyed earlier was due to the NY cast, director., and designers, rather than the material. "Three Bedroom House" is the only song in the score that I find to be completely successful.
Funny that you bring this up. I have an acquaintance who runs his own horror/dark comedy film company, and I told him long ago that his group could have a lot of fun with Bat Boy. I wish he'd pursue it and let me be on the creative production team!
