Seriously? They need to gut the thing and make it into a LWTL type deal, with windows into the tank unobstructed by screens...
Lol. That's
sorta what it originally was.
The vehicles, you originally sat forward in and you could see in all directions instead of the seashells that act like a static doom buggy, only pointing to one side. Having said that, the space is pretty compact because most of the original ride was looking into the tank and was intended as the grand reveal of the tank (meant to be the ocean) and your arrival at Sea Base Alpha.
It was part of a larger experience that was all where the queue now sits.
Here's a video of the original complete experience after that initial "beach" room line area (as it looks today) you'd go into a movie and that's where it all started:
Looking back, the hydrolator effect was a little cheesy and the whole thing was due for a modernization when they changed it but you really can see how much harder they used to try when they were dealing with sponsor money in Epcot. It's basically another (though far less dramatic) Imagination-style cheap redo.
I mean, the transporting effect in Guardians is cool. It would have been better if the apparent animatronics from the concept art had made it... and if it had gone to Hollywood Studios but I'll give them credit for not completely cheapening out on that
entirely IP-driven project. They clearly
can still do things well in this park when they're motivated to.
As for The Living Seas, though, they literally replaced 80% of the complete attraction from that video with a giant never-full queue to accommodate a 3 minute ride of screens.
Even if they were to just gut the ride system and make it a walking path into the main attraction with the windows all visible,
I'd count it as an upgrade to the pointless Nemo ride that's there, today.
... but then there'd hardly be any IP in the pavilion and they can't have that, now can they?
