Call me a heretic, but I thought the 20K Leagues ride at Tokyo DisneySea fell a little flat. The ride system was impressive and the queue was fantastic, but the "wet for dry" effects out the portholes weren't quite as succesful as the real porthole view in real water you get on Disneyland's Finding Nemo Submarine ride.
Okay I won't call you a heretic but I will
STRONGLY disagree with the main premise of your statement.
First lets talk about the vehicles. It's not just the ride system that is impressive, it's also the incredible detail and aesthetic quality of the vehicles themselves, both insice and out. Secondly, I challenge anyone to find dark ride sets built in the last 20 years that are as lavish, detailed,and elaborate as TDS's 20K. The quality of artistic finish alone is better than 95% of anything out there today when it comes to dark rides. After 15 trips through the ride I know I have not noticed every prop and set piece in that building.
You say the wet for dry is not as effective as the Disneyland or WDW version? I can't disagree more considering how, as a child even, I would look through the porthole in the subs at WDW and see the top of the water. In TDS there is nothing, other than the knowledge that you are in a show building without water, that breaks the illusion. The lighting is perfect, the scenic treatments are perfect and the colors are realistic. Add to all that the nice interactive feature with the spotlights, the unique seating arrangement in the vehicles, the interior lighting, sound etc. I am still in shock that anyone has anything negative to say about this ride. As an adult I found myself naturally suspending disbelief as if I was truly traveling in a submersible deep under the sea. Trust me, being a ride designer myself I can tell you it's extremely rare to present us with a product so convincing that we don't see the backstage stuff. I rode this ride at least 5 or 6 times before I even began to question anything with respect to technique, technology, design and execution.
WARNING - 20K PLOT SPOILERS!
And the plotline was a bit odd and rather bland yet utterly predictable, and I don't think it would be a big hit with Americans since it's not a thrill ride and it has absolutely no Disney or Pixar characters. The little alien guys were just very odd, and their helping hand at the end became even weirder.
I don't speak Japenese so I didn't understand the dialog. That didn't detract anything from the experience for me at all. Yes the storyline is predictable. Why wouldn't it be since Jules Verne wrote the story the ride is based on back in the 1800's? If you want to go by your logic I'd say the plots, or lack thereof, of Haunted Mansion and Pirates are bland and predictable.
The helping hand at the end of the ride as well as the odd aliens can be modified to reach the European and American audience if need be.
If Americans won't like the ride because it's not a thrill ride than they better not green-light Mermaid for Florida. It's already too late for California however. Personally I don't care if they tie in Pixar, as long as they bring this ride to the states, detail and quality in tact.
The Journey To The Center Of The Earth ride, on the other hand, was fabulous and a total home run. That one would be a huge hit here, even without a Disney character tie in.
This I can agree with 100%!
