I think a great opening would be for some event happening in Summerville. Some scary event. Teenagers making out near the mine and shit goes down. It’s a local spot for make out parties. It goes badly. Cut to far away. Ray Stanz(whose face we maybe don’t see) is busy tinkering with something in his bookstore. Suddenly we hear a familiar sound. He hears it too. He slowly walks towards an old desk, opens the drawer and peeks inside. We see his face for the first time now. An expression of excitement and almost sadness appears across his face. He picks up the device inside the drawer. It’s a PKe meter and it’s going batshit off the charts. And then it dies(symbolism). No readings. No nothing.
Ray reluctantly puts the PKE meter back inside the drawer(more symbolism). He starts to walk away, resigned to the fact that this may have been a malfunction or blip, but then we hear the noise again, cut to Ray as a big smile comes across his face. We hear the familiar opening to the Ghostbusters theme song…as the paranormal enters the world once again.
