A Broadway musical?  Really?

The more I think about it, the less I see a real Broadway audience for that show.  It’s an awesome book (from what I hear) and a fun movie, but it is (a) beyond dark and (b) super absurd, neither of which really seem to bode well for mainstream audience approval.  I could imagine them consistently filling a small downtown space, but Broadway?  Are they going to try to sell this on the basis of the eighties songs?  If they do, they could have a mini-disaster on their hands.
