Shared Universe or Clean Slate on Ghostbusters

Just looking at reports on changed plans to have a Channing Tatum Ghostbusters introduced as competition for the Kristin Wiig vehicle that is coming out this summer. Apparently the new male version won't be this decade, and I could not care less. There is tweeting and clucking that bemoans the idea that these movies might not all connect, Marvel-style. The time to think of shared universes was before Feig e-mailed Amy Pascal with his idea that humans have had NO evidence of the afterlife and the 1984 Ghostbusters never happened. The Orkin pest control idea was already suggested in the 2009 original cast video game, wasn't it? The old traps did not have to look like bear traps, since the essence of a ghost has nothing to do with apparent size. The original props could have been made available if Wiig and team simply bought into the franchise as a branch of Ghostbusters. They could have moved into a property across the street from a Westboro Baptist Church type of organization and might even find ghosts or possessions there. Maybe their branch doesn't have to be in New York. If Dan and Ernie Hudson just were seen in an ad that might have been enough. There are plenty of satirical reasons to justify people not believing in ghosts despite there having been huge events. There was no twitter nor smart phones in 1984 or 1989. Cell phones weren't even common when The Real Ghostbusters show ran. It is possible that ghost believers might be treated as 9/11 Truthers. That is what should have happened. Speaking as a moviegoer.
