Seriously, it's astounding how poorly the aesthetic that was in circa mid-90s/early 00s has aged, not just in Disney but in pop culture in general. Every generation of aesthetics has something about it people aren't exactly eager to bring back (e.g. the strange color palettes of the 70s, some of the 80s more questionable 'neon' choices, etc.), but that particular era had such a busy, crowded look and a vibe of trying to cram far, far too much visual information in one place, whereas right before it and now after it you see more of a preference for sleeker/cleaner designs (I'm thinking DisneyQuest and the original Downtown Disney West Side as examples of that "90s aesthetic" as I write that out). No greater contrast than CommuiCore to Innoventions, or yeah, the complete closing of the open look of the original Imagination pavilion...man, no wonder EPCOT got hit the hardest with that hammer than any of the other parks, and astounding that it's taking this long to finally undo a lot of the worst of it. Doesn't mean what comes next will be perfect, but still.
Great, now I want to read a research paper or book on what social forces informed each generation's overall look, and see if there are reasons that make sense and that I can sympathize with.
