I get what you're saying. Epcot was never a favorite of ours - we dubbed it The Boring Park, but we would always go for one day (for The Seas and Nemo ride and pumpkin funnel cakes, mainly). But then on our last visit, my-inlaws met us at WDW for a couple of days and we let them choose which park we would go to on their last day - they chose that one. Because we didn't want to rush through in case they wanted to stop anywhere, we really took our time and meandered and for some reason, it "clicked". I don't know what it was, if it was a stop and smell the roses moment or just experiencing more of the sights, but we're looking forward to our next trip and we'll plan two days (and possibly more nights) at Epcot.
I think it's one you really need to slow down to enjoy. Actually, one of my favorite moments that day was when my FIL and I just sat on a bench with my youngest, waiting for MIL, DH and DS8 to come out of a show (we weren't interested in it). My FIL and I get along fine, he used to be my boss, but we don't get much chance to talk, so I loved the one one one time with him while we people-watched and discussed Disney and how they are unbeaten when it comes to designing their parks. It was great seeing Epcot through new eyes.
