I depise it whenever Disney decides to kill off a good attraction for something less costly or less reliant on audio-animatronics. EPCOT has suffered the worst because of this, losing everything that made EPCOT wonderful (except Spaceship Earth, which they keep threatening to kill and Wonders of Life, which is being treated as dead though still very much intact). I am a bit surprised no one has mentioned the Tiki Room, though. That Under New Management mess is truly awful...even if it does have some of the best new audio-animatronics.
And am I the only one who thought Mr. Toad was a day-glo nightmare? I'm amazed how many people loved this attraction. Disneyland's is great, and I could ride it all day; but the Magic Kingdom version was just plain lame. I'm sure I'll catch a lot of heat for this, but what was so wonderful about the Magic Kindgom's Mr. Toad that I'm missing? It's like when people say Test Track is such a great ride. I practically gag every time I hear it, especially when compared to what it killed off to be there.
Bring back EPCOT circa 1995!
