With respect, advertisers and film studios are also aiming at entire demographics rather that specific fandoms. As far as selling things go, they are also trying to get people to change their buying habits, which older customers are less likely to do.
Having said that, I am quietly hopeful that the new Collinwood would indeed be new. I'm not interested particularly in seeing a carbon copy. When I go to see a new version of Dracula, then an imitation of Bela Lugosi or Gary Oldman would make me feel cheated.
