I felt the post I was responding to wasn't talking about the last 20 years, but the last 5-10. Which has included: Avatar, SGE, TSL, Cosmic Rewind, Ratatouille, Tron, MMRR, and yes, the disappointing EPCOT refresh. A few of those attractions I believe to be on a similar scale as Everest, and I have hard time thinking of any attractions from the 2,000's outside of Everest that are on the same level. But my memory may be failing.
I think many of those more recent high quality attractions and investments that give me optimism about the new projects.
Yes. The last five to ten have been where most of the catch up has happened. That is why the parks are quick to replace so much that they see as stale. They are still playing catch up for the first decade and a half of meh. New Fantasyland kicked off this knee jerk rush replacement mode as the first response to the Wizarding World.
This is why the last five to seven years of the 20 are so heavy and you have a hard tim remembering much after Everest.
