I didn't really like the idea of the whole “entering hell” thing either. It seemed kind of cheezy and un-Ghostbusters-like. The notion of inventing a device to send you to hell doesn't really appeal to me. Like I said, it sounds cheezy. The time machine/other dimension machine has been used too many times before. It's something writers use when they have nothing good to write about. The fact that hell is crowded or whatever seems like a good idea for a plot, but it needs to be worked out. Perhaps just a big vortex or something hidden in a church or something. Maybe the priest is mad and he opened up this hole that brings the dead back. I really don't know, but anything would be better than actually going to hell.
As far as the script review, it sounds like the guy liked everything except the new GBs. In my opinion, the introduction of a new breed of GBs would be nice, but it the original GBs would still have to be the main focus. As secondary story could be the introduction of new guys/girls, but people want to see Ray, Egon, Winston, and Pete. Saying that, I think it would be better to have two “interns”. They are just sort of there to help them out and in the end, they help save the day.
On the topic of the new guys, I have to agree with this STAX guy. I don't like them and I didn't even read the script. Body piercings? Hot latina girl? Handicapped genius with a big head? How stupid is that? They are so not Ghostbusters. The thing that apealed to me about the originals was the fact that they were just regular people. They didn't have any special look about them. Regular schmucks out to save the world. That's the way it should be in GB3, if it ever gets made.
Overall, from what this guy tells us, there is potential. This was a first draft, so things would definitely get worked out.
