Based on the script I read, it's probably better it was never made. They go to hell but nothing is different; its NYC with the people going on in their everyday lives but doesn't have a clue they're in Hell except for Ray. Ray goes on a crusade to prove what he sees is real, it wasn't interesting. Also the script had the reset button again, where every member are doing other professions.
I wanted the script to be like the cartoon; where the GB are established and its another adventure, but the twist that Signorney Weaver was Satan??? Urgh!!! It just felt like going through the motions and kinda making a remake of the first one in the worst way. I read it online. It's titled "Ghostbusters GO TO HELL"
Every time I planned to track that down an read it I never did. Sounds like I didn't miss much. But there has to be other versions. The video game script is decent and probably needed just one or two polishes. (there's two versions of that too.)
I would open with Venkman having died getting people out in 9/11 woth Oscar working security on the new ground zero development. 9/11 is the elephant in the room where New York Apocalypse films are concerned, especially when you look at the end of the first film and how it's described in the second.(actually I would open on dana and Peter in the same room, only realising they aren't quite interacting because he's a ghost after a few minutes.) So put it front and centre in a positive way then move on, with Peter finally making contact from some heaven dimension to warn the guys and be happy to see his son follow in his footsteps (fulfilling Sigourney's stipulation for taking part)
Egon is researching at cern, makes an appearance as a disembodied voice (possibly as a commentary figure alongside Venkman) and it's basically down to Ray and Winston to build the new team (they aren't out of business, but after the 'psychic shockwave' of 9/11, there's either less ghosts or people aren't so pro imprisoning dead loved ones...I should iterate that at no point should the twin towers be used as a source for ghosts, cos while it's an elephant, it's git be done right so as not to be a joke.) with Oscar. Then you get your equal opportunities because I don't think ghostbusters have to be guys, (the egon janine stuff actually works better if you gender flip it in some ways)
People and ghosts come in good and bad, and the cast gets to do their thing, in what is basically a serious film that has funny people as characters (like The Martian. Or Constantine.)
There's some good and bad in that idea, but hey I haven't had years of writing in Hollywood, and I kid you not, I literally dreamt this idea.
Oh and yeah no one asked, but at least I have thought how I would do this story before I get disgruntled at how anyone else does it.
Hope someone found that concept entertaining, even if just to laugh at me for having it (or having weird dreams about movie sequels)
