I don't think it's a matter of what people want to see, I just think it's a matter of quality.
I haven't seen the show yet, but I have heard from literally everyone that it's a carbon copy of the original with less than stellar performances. I can't imagine it getting strong reviews, and their ticket prices are obscene.
I think that's what will ultimately kill it in a year or so.
