At this point, I think any new ghostbusters movie would be a reboot a'la superman/Spider-Man/batman/hulk/fantastic four (really?)/Star Trek.
I heard rumors a while back that goonies could get a remake which would be terrible.
Hollywood should remake citizen cane, Lawrence of Arabia, gone with the wind, rocky, harry potter, and transformers while they are at it. We could also use a new version of the three original Star Wars.
