Obviously, it’s a hot property right now and there are a lot of potential first time customers in New York, but I do wonder if there is a danger of over-saturating the market if Broadway is the ultimate goal."
I think having it play off-Broadway directly before Broadway would be unwise since it would probably take away from Broadway audiences, and it also seems to fit better into an off-Broadway space (I also haven't seen it). But I don't think the Boston/Chicago stops would hurt it. If anything, it would increase word of mouth for American audiences and prove that it's not just a UK property. (And also Ain't Too Proud also did quite a few stops before reaching Broadway and it's doing just fine, granted it's a vastly different show and also had a built-in fanbase, but I think the point still stands.)
