Assuming they market a return of the HH as a 'new' attraction for 2023 (unless they also bite the bullet and get a permeant flat ride in place) I do wonder if it might get a surge of a second coming of popularity among the GP not seen since it first opened, just look at old footage of the park and seeing how big the queue line was getting into the place in fact I can remember when I first went in 1997 that the queue was slowing moving its way through the portrait room, could it be that the graveyard extension queue line might be left permanently opened unlike now when it is only rarely these days? I was lucky
I agree that it would be downright impossible to return back to its original 1992 state though I could see that if they are to bring back several old features of the ride such as the giant, they could be updated and advanced such as the giant have blinking eyes (not sure if the original ever did) or perhaps the spider scene could have a peppers ghost effect of many more spiders climbing up around the wall which would make that scene far more nightmare worthy if you have a fear of spiders. This has happened with likes of the Haunted Mansion and other dark rides around the world so I wouldn't be surprised if Towers were to do this and if JW is playing a part in this project then I have no doubt that things that he wanted effects wise which were difficult to do back 30 years ago could easily be done today with the technology we have now he'd be determined to see some of these things finally become a reality. Yeah, kind of like what George Lucas did with the original Star Wars trilogy by adding many CGI elements to them which many hate though on this occasion, I'd think we'd be all opened armed for this to happen.
IMO, I would like to see an actually storyline for the ride which honestly adds a lot for any ride, look at how much we love Hex because of the storyline, a new HH would benefit for a new story which I think many guests do appreciate rather than something like Thirteen which even to this day I still have no clue what the backstory for the ride is other than some routine maintenance work that goes horribly wrong or something stupid like that. Can someone correct me on this? Also, I don't think 1990's cheese won't exactly fly with today's audience mostly the kids who want hardcore and not something like GG, they'd want a real scary HH which in some ways seems to be what BPB are doing with Valhalla to make it more darker...that is if they can get the damn thing to open so who knows what tone they'd be going for here for Duel?
