I think those who grew up with whatever they had to experience at the time, or first timers experiencing things even as an adult for the first time, will forever be oblivious to what was “once there.”
Me, for example... I grew up with Food Rocks and Ellen’s Energy Adventure, as opposed to the OG attractions of before. I dont get OGs no matter how many videos I watch (Even tho they fascinate me), and when I saw construction walls up at Food Rocks to make way for Soarin as a kid, I literally Bawled my eyes out because I loved It so much.
Same with OG Test Track, in comparison to world of motion and current TT...
So here I am today not as much of a fan of Soarin, Guardians, and Frozen taking over. But this next generation will love these attractions as much as I loved the attractions of my generation, and the generation before me.
Nostalgia is nostalgia.
Epcot is a park where I believe a majority of fanboys are more obsessed with its history rather than what was actually there. The history is so rich and detailed, unlike any other theme park in existence, because it was so unique... It’s easy to drench ourselves in the history of Epcot because it’s so fascinating.
I dont even know what I’m talking about anymore. Point being: Each generation will like what they first experienced the most, because that’s what they got to enjoy.
This isn’t true for ALL things at Epcot. But it’s certainly true to the average park guest.
