You say 'all the way back' as if it were a good thing and just part of the journey. No, around 1994 is when the turn was made, heading the wrong direction. All you are doing is pointing back to when they made the turn... down the wrong street. That's the period that brought us innovations, the Imagination fiascos, the loss of sponsors, the lack of refreshes that doomed Horizons and WoL...
Earlier they tried to bring the characters in, but dressed to EPCOT, to address the 'where is Mickey??' problems.. but its not adding of foamheads that broke things.. it was where they were headed.
Now 20 years later we see where it's gotten us... a further stale EPCOT that is now punting all together on it's very premise. So to everyone who says "who cares.. its something new" - fans from the 90s have something for you... a history lesson.
