Whatever exec(s) is/was pondering this decision does not see the quality and popularity of the ToT.
It is a quality ride. It is a great ride. And I'm not alone in saying that, proof being that it does very very well in guest satisfaction. In my opinion, it's so great because it's not only thrilling, but also pulls you into a strong, cohesive, full story. So many other rides sacrifice story for thrill, and not only does ToT avoid doing that, it makes the thrill an essential part of the story. They are inseperable. That makes a great ride.
It's also hugely popular, drawing long waits! It gets good reviews and ratings from guests. And it's unusually popular outside of these circles. When other people discuss drop rides or drops in general, ToT often comes up. At least where I live, and I live many many miles from Florida, by the way. It's built a name, it's built a legacy. It's become a draw to WDW.
Finally, I shall say this. I have absolutely no doubt that imagineering could turn the ToT into an excellent GotG ride. But the big question is... WHY?! Why would they do it?Replacing Maelstrom, Snow White's Scary Adventures, The Great Movie Ride... that's one thing. But replacing a ride that's not in the least bit outdated, that's popular even to those outside of us park fans, that still draws long waits, that gets great guest reviews... I am at a loss. I cannot understand why they would sacrifice something so universally good for anything, anything at all, no matter what the replacement is.
My only conclusion is that the exec(s) is not very knowledgable. Perhaps they've never been on ToT. Perhaps they had absolutely no backround in theme parks before being put in charge of them.
