I definately think it could have gone in mny different directions had it had a higher rating. The way it is now, Ghostbusters is timeless classic, with no need for change. Had it been more vulgar, some things may have been funnier, but others, very stupid and un-needed, and had the rating been R, the franchie probably, infact most definately wouldn't have made as much money, or spawned even a thought of a cartoon or a sequel.
