Then I'll answer, if that is truly the case.
How the heck is it the same ride?
It's the same ride system, the same ride layout, and the same premise. (Research Submarine encountering vignettes of undersea life) Only thing added was a story involving undersea characters passing through these same scenes. The scenes are different yes, but there are countless that are the same, if not expanded upon. Such as the Graveyard of Lost Ships, The Reefs, The Dark Abyss, and the Undersea Volcano. Only Atlantis and the polar ice caps are gone. (And at least they pay tribute to Atlantis in one of the large opening scenes.)
When you say longer you are insinuating that they added more trakc or something all it is is that the vehicles move slightly slower.
No, I state longer because the ride time is longer, by at least two minutes thanks to longer show scenes.
The storyline is a watered down version of the films story just like the epcot ride
I'll give you that, but it still doesn't interfere with the base ride it's always been. (Passing through undersea vignettes along the lines of Jungle Cruise, Haunted Mansion, and Pirates)
If anything it's perfect because while getting you involved in the characters plights, while not interfering or getting too involved with the experience of passing through different scenes in Liquid Space.
"improved effects and sound?" sound maybe but effects? They took out all the set pieces and replaced them with vidoe screens it looks like someone flooded a best buy full of water and sent a submarine in there. Plus there are enormous chunks of the ride that are just pure darkness where there used to be scenes. Its BS.
Yeah right. Being intimately familiar with every rock and fish in both of the Submarine Voyage attractions (Being my favorite type of Disney Attraction) and scrutinizing every detail on each of my seven rides on it, I say with no hesitation that the show sets are infinitely superior in the new attraction. The crafting involved in the many layers of sets that are integrated with glass and scrim layers. (There are no "Video Screens" only layers in the set which are transparent and being projected on.) The blending of Wet and Dry scenes are amazing, and a lot more effects than the previous incarnation, which featured practically no effects other than lighting and air.
Was the old Submarine Voyages better?
I think so too.
Is the new one "BS"?
Heck no. Apart from being a darn good show, it's also a massive achievement to save this ride (An achievement of which I spent most of my life wishing to come true.) and will carry out the spirit of adventures through liquid space for generations to come thankfully.
