Keep 'Em Coming Back

I see a bunch of former Sex And The City writers (including an old acquaintance, Cindy Chupack) are writing a weekly, live comic soap opera. I guess it's right up their alley, but I have to wonder if they can draw a regular audience to the theatre to see the show.

Serials work in books, magazines and TV, but isn't it asking a lot for an audience to check in regularly on a live show?
