There are only two things that could potentially save a show as bad as BROOKLYN:
-an amazing score (which BROOKLYN doesn't have)
-big stars (which it doesn't have either)
As much as the music might appeal to younger people looking for something "different" like yourself, most people have never even heard of it. Other shows that have been in similar positions had a few other things going for them:
Urban Cowboy - an insanely sexy man as the show's logo bearing a greased 6-pak, plus the "closing night" that ended up not being the real closing night - people wanted to see what it was all about and if it really was terrible.
Dance of the Vampires - had a big Broadway star that hadn't been back in NY performing since the 80's - he has some very rabid fans. As the show went on, again, people kept going to see it to see if it really was as horrid as people were saying it was.
Taboo - Rosie O'Donnell AND Boy George's name was attached to it which sparked more interest than usual in a Broadway show from people usually not in-tune with Broadway. She also had an INSANE "taboo street team" and spent ridiculous amounts of money on press and advertising.
BROOKLYN is virtually all newcomers - from the writers to the cast. They have VERY little, if any press or advertising. People coming to Broadway from out of state who maybe only come once a year aren't going to gamble their money on a show that they've probably never heard of with writers and a cast they probably haven't heard of. And as we all know, tourists are what drive the Broadway community, most of the time. BROOKLYN isn't completely doomed, yet. It's running costs are so insanely low that they can scrape by with making such little money, but we'll see how long they continue to wait it out...
