I'm perfectly okay with an all-female team. I'm just really bummed that this won't have ANY connection with the original universe.
Ghostbusters, as a name brand and franchise, has always been about that world and characters. That's what people love. Sure, the idea is golden (sci-fi/horror/comedy mashup) but without the world around it...it would have failed.
While I'm obviously going to see this reboot, I will always wonder "what could have been" with an actual film continuation in the original universe.
This new film will be interesting to follow. I wonder what the tone will be? The director mentioned it being actually scary. I'm looking forward to see what new ideas they will bring to the table, but I'm still really bummed that it isn't in the same world as the first films.
