Saw this for the first time this weekend - posted my thoughts here
FYI, Rosé was in the show when i saw it.
Having now seen the show, I'm really surprised there was ever talk of bringing it to Broadway. From what I can tell, they're already in a comfortable position: they have a decent-sized house that they seem to be filling fairly well, pretty much at Broadway prices (albeit on the lower end), while probably making a killing at the downstairs bar. And costs are somewhat lower because they're Off-Broadway.
The only advantage to going to Broadway would, presumably, to be to make more off the larger numbers of seats. But it seems like an EXTREMELY risky move for an uncertain reward. Sure, you could say that about most Broadway shows, but this one is in the rare position of already doing well right where they are, with no pressing time limit on their lease. And meanwhile, the demand is strong, but not so strong that people are lining up for cancellations.
Meanwhile, the show just has a scrappy, Off-Broadway feel, and I mean that in a good way. I feel like bringing it to Broadway would put more scrutiny and higher expectations on things that are not necessarily designed to be the show's strong points.
