Another Voice said:Again - how much of a ride's popularity is because of the show itself, and how much is because "we're already here, let's go on this one". The concept of good enough has a couple of different levels.
Dozens and dozens of better animal parks have rides similar to Kilimanjaroo. There's not a single element in the entire show that truly's unique, nothing that gets people to say "I've never seen that before" or "that's impossible - how did they do that". It lacks the "magic" of real Disney attraction: Kilimanjaroo appears exactly what it is, a bus ride around some cages. But the public expects Disney to present them "dreams made real": haunted houses and rocket trips and flying with a beloved character from childhood. All Kilimanjaroo offers is a really bad episode of the Kraft Brothers ("Com'on Martin - let's go save Li'l Red!!")
'Soarin' - gee, 'Star Tours' was popular for a long time. But it's a walk on now. All rides that are basically movies grow old very fast. Already the ride's popularity is slipping at California Adventure - and it's not like there's a lot of competion in the park either. 'Soaring' lacks a couple elements that would have made it better attraction. There should have been a real show there. At the moment it's a movie theater with a gimmick. They don't even bother to hide the fact that's it's a theater.
But most of all, it lacks the emotional kick in the gut that the best Disney attractions have. It's the "I've always wanted to do this!" antcipation and then delivering on that promise. You feel like you've gone through a haunted house when you exit the Mansion. You mind tells you that it's only an amusement park ride - but the your hair really stand up on end, those special effects are so believable that it's easier to believe in real ghosts...it all just seems so real yet there no way it possibly can be.
Or the 'Indiana Jones' Temple ride. It feels exactly what it would feel like to be in an Indiana Jones movie - the speed, the noise, the confusion, the over-the-top effects ("is that three story high skull really spitting flames at us?"), the phyisical thrashing and the "ohmygod - it's THE BOULDER!" moment that makes everyone scream even after ten years.
To do that takes a lot of skill, a lot of talent, and even more than that in hard work. Disney knows this, they know the was to make a great attration. They just aren't willing to put that effort these days. 'Tower' isn't fully developed enough to be much more than a facny drop ride, 'Soaring' is an IMAX theater with fancy chairs, and if one more movie spits water at me, I'm swearing off 3D films forever.
You'll still ride Heimlich's choo choo train though right.
