Here's the thing.
I do believe TL, right now, is a complete mess. But there's a deeper problem underneath it's chaos - it's that it doesn't have a unified vision, IMHO. Frontierland, Adventureland, Fantasyland - they all have a really strong sense of what they should be. TL should be the same - at least, that's what Walt and Co. originally intended, but right now TL is a submarine voyage to find a fish's dad, a toy playing against his nemesis, a Best Buy, an old movie and two space trips (one of them based on a story that happened "a long time ago" -how futuristic!). All against the shadow of defunct attractions (the cherished PeopleMover, Mission to Mars, and the ghost of the Carousel of Progress).
Every now and then I think - what would I do differently if I was in charge? First -I'd drop prices and raise CM's wages (but I digress). About Tomorrowland - that's the part of the park I'd definitely focus my efforts on. I guess there hasn't really been a single version of the Land that is satisfying, except for TL '67. Which was focused on, well, the future - a moving target that never came to be. But oh, what a future it was!
So, I was considering the old Mary Blair murals, and suddenly, I got the idea. There's a vision of the future that hardly ever changes: the future as seen through the eyes of a child. That future would mean world peace, understanding, cooperation, friendship and excitement. It's not a moving target - it's an ideal, a true goal, a real vision.
Sort of Fantasyland meets EPCOT Center (the old one).
That's what I'd try the new TL to be. If its true that the old murals are still there, I'd rip those horrible, cheap things that are covering the Mary Blair ones and start from there. The unifying vision would be peace through understanding, knowledge and happiness. Forget Star Wars; that's the real future, our real challenge.
The old Carousel of Progress could be brought back to its roots and have rotating displays of technology. Create 5 stories of what the future may be, and keep replacing a scene every 4 or so years. Sort of like Spaceship Earth - but don't let the future keep up with you - just keep moving (there goes Finding Nemo again).
Keep Space Mountain, but update it with the highest tech possible and focus on transportation and adventure. Get the subs back, change the theme to underwater colonies, exploration, ecology, etc.. Turn Buzz Lightyear into a solid D+ ticket dark ride, focused on great achievements of mankind and possible future ones - and keep an interactive element, so it doesn't get boring. PeopleMover - think about a really novel means of transportation - solar energy, whatever - and send it back into operation. Build something on the empty space between TL and Main Street - perhaps an updated Mission Space E-ticket? Focus on movement, data transmission; use NFC and Wi-Fi to deliver new interactive experiences all around the place (but don't even try a MyMagic+ or whatever it's called Big Brother thing! Send information, trivia, ideas - engage the crowd through technology), fill the land with fiber optics that make the area become alive at night, have different groups play in a small arena where the Magic Eye Theater now is, remove the rockets, send them back to their rightful place... and yes... style it all just like the murals of Mary Blair. Forget about all white 60's style future, or brown and algae green of TL '98.
The future is more than futuristic or abstracts looks and shapes, or about an (admittedly awesome, great, epic and incredible) movie trilogy that has no place at Disneyland; is about our capacity to love and get along one another. That's what we should look forward to.
