I don't think its a weak attraction, just the weakest of the Towers. DCA's was my favourite, so Paris too must be as they are the same. Tokyo's is awesome, but a little more cartoony. The DHS is a blast, but I do prefer the faster paced attraction that came after the original. There's an intensity and growing doom that I feel in the newer versions. I also much prefer the false drop with the floating/dropping elevator rather than the window morphing into the window from the opening and breaking. It feels like the better ending to a scene.
While I appreciate the technical marvel of the trackless 5th dimension room, I feel its wasted as the effects/scenery in the 5th dimension room are pretty corny and dated. Plus, I hate the amount of time and shaking it takes for the car to settle into the drop shaft after passing through the starfield door effect. Its like building up to a big magic trick and having the magician take a pause to readjust their hands and gimmick before the "Ta-Da" moment; it just sucks the intensity from the ending.
I also love how the future versions of the attraction have you start/end in the same place with the same bellhop.
Story-wise, I think they cleaned up the subsequent versions as well. The original has narration in the elevator about us going into an episode of the show. But we're already in the hotel. And in the elevator. Is the elevator taking us into a TV show? But the floors are hotel floors. A minor nitpick, but its there. The newer versions frame the entire experience as if you are in the show. They also switched out a lot of the show imagery with imagery which supports the ghost story. So instead of it being about entering an episode of The Twilight Zone TV Show complete with floating elements of the opening credits, its about the ghost story of the hotel and uses the show as a framing device.
I totally understand people who prefer the original. I did until I went back to DHS and realized that it felt badly paced and not as effective to me compared to the version I had been riding more recently. There is no arguement the queue and facade are miles better in Florida, but as for the on-ride experience, the newer DCA/Paris/Tokyo ride systems are better executed IMO.
