First of all -- this is supposed to be about ride disappointment.
Not rides you don't like.
Not rides you think need to be updated.
Or especially rides you think you wouldn't like so you refuse to ride.
Disappointment would be if you have higher expectations for an attraction and are let down by what you experience.
If you thought Nemo was going to be the best dark ride every... yes you might be disappointed. But who thought it was going to be much more than cartoons in a fish tank?
I have never been on Sorin'. I believe I "may" be disappointed because it's just the same 10 minute movie over and over. But I can't say for sure -- CAUSE I'VE NEVER BEEN ON. I can say I'm not super interested though.
I don't like COP/SSE because they are HUGE time wasters. But that's not a disappointment. I know what's going to happen in each. And I won't make the mistake of going again. Please SSE rehab add SOMETHING interesting to this attraction.
I was very disappointed on Dinosaur. I was totally expecting the emersive experience of Indy and I didn't get it. Maybe Dinosaurs are to fantasy. Maybe it wasn't life like enough. I don't know. But for being the EXACT same, it really fell flat.
My expectations weren't high for Tiki Room Under New Management. But it was so bad that it was below my lowest of expectations. So it is also a disappointment to me.
The worst was Disney Studios. I was so EXCITED as a kid to see THE MOVIES COME TO LIFE. I expected there to be sets and filming and have the Hollywood buzz throughout the place. But it was a series of 7 shows and 2 rides. I know it wasn't finished at the time. We went the first winter. But there were no sets running at the time (just missed seeing Mickey Mouse Club for the season). And the Backlot tour was 2 hours long. But they didn't really show you anything. Just the same preproduced shows that everybody saw. There was no real highlight to the Studios when it began. It's getting there now, but an overhaul is still much needed.
One attraction that I've been on that can be disappointing is the Jungle Cruise. A skipper can make or break it. This is one attraction that can literally be a totally different experience each time. I could see a few others being this way, but how can somebody say that the ride on IASW is disappointing??? What did you think you were going to get??? It may be boring, but not disappointing.
I guess I don't see the distinction you are making. If someone doesn't like a ride, usually they are disappointed they didn't like it. If someone feels a ride is outdated, then they would be disappointed it has not yet been updated.
The whole point of going on an attraction is the expection that you will like it, otherwise why go on it. So if it happens that you don't like the ride, the most logical reaction would be disappointment, unless you rode it for no other reason thean to quench your curiosity. Now, if someone rode Dinosaur, and didn't like it because they don't like dinosaurs, than that shouldn't count as diappointment.
I don't think anyone thought Nemo would be the best dark ride ever, but this is not nessisary to be disappointed by it. I thought is was going to be a short dark ride with an immersive theme utilizing advanced technology to allow the animated fish to swim with the real ones. Now, I haven't ridden it myself just yet, but I've seen the video and it looks great IMO. And who's to say everyone who rode it and were disappointed by it had the same information going in.
So you aren't disappointed that COP and SSE wasted your time? Why would you ride them in the first place if you didn't think you would like them? If you rode them expecting one thing and getting something else, is that not disappointing?
So if you can't be disappointed by an attraction you don't like, can you like an attraction that you are disappointed by? Does that mean you like Dinosaur?
If someone has never been on a ride, how do they now what they are getting into, especially with a title like Small World which does not fully explain the contents of the ride. Why would Disney even build a ride people would be bored by? Although not everyone is bored by it, i like it.
So can someone be disappointed by a ride they don't, I think so.
As for rides I am disappointed by:
Tiki Room: I was disappointed by the frivilous use of characters and the all to common pop culture bandaid
Winnie The Pooh: Disappointed it was nothing like TDL's version and had less character than the previous inhabitants IMO
Buzz: Liked it ok, was disappointed by the feeling that I was on a themepark ride unlike other Disney attractions which make you feel like part of the environment
Test track: Only disappointed that it broke down two of the three times I tried to ride it.
Imagination: Disappointed that it was so boring, every time the car stopped I wanted to break loose screaming and crying. Disappointed in the lack of immersive environment and fantasy aspect the first one was know for
Maestrom: Disappointed it is so short, the queue area is so bland, you move too quickly by many scenes to actually enjoy them, and the the unload area looks better than the rest of the ride.
Rock N' Roller Coaster: Disappointed it's a looping rollercoaster in the dark with aerosmith music (just kidding)
