There are always those nostalgia-focused souls who are saddened by any change, even changes that actually improve the attraction. Star Tours comes to mind.
Then there are those who complain bitterly when certain good features are removed from an attraction, but over all the change is an improvement. Spaceship Earth comes to mind.
Finally there are those who rightly complain when something far superior is removed in favor of utter idiocy. The new TTA narration is worse in every way. Even if it's similar to some old original narration, the last one was far superior, and should have been kept. And should be returned. And could be returned very easily. I, for one, have not complained about the new version of any other attraction other than to say that I preferred Jeremy Irons' Spaceship Earth voice over Judi Dench's. Nevertheless, I fully acknowledge that the over all upgrade to Spaceship Earth is superior to the old version, and I like it.
The new TTA, on the other hand, has no redeeming qualities. No honest and informed person with an IQ above that of a tree sloth, to my knowledge, prefers it. In fact, it has the fleeting quality of an interim version that somehow became permanent. A few switches should be flipped, and the former version brought back.
