The lens of nostalgia always makes people look at things more fondly, but in this case, the soundtrack is a masterpiece and the story fits everything that Epcot was about. It was the perfect cap to a day at Epcot. Since 1999, each of the original pavilions has changed to different degrees of controversy, and in my opinion, it's the last piece of the golden age of Epcot. I think some of us, myself included, hang onto it tighter for this reason. It seems like if you grew up watching RoE, the majority love it and a minority think it was time for change. Feels like it's the reverse if you're more of a WDW newbie. That's only a small sample size of this corner of the internet, but I think you've got the general idea.
Granted I'm focused more on Entertainment than Attractions, but what happened to the rest of the pavilions? I know Donald and a little COCO in Mexico, Elsa in Norway and Ratatouille coming to France.
