Hey MM! I'm sure that initial viewing has something to do with it. I remember going to WDW when Epcot was being built as well as when it was brand new and so I've got an emotional connection to the original... Heck, I even still miss Kitchen Kabaret.
mom2rtk, it came out in 1982. IMDB's page is
here. OK, it is a product of its time and kind of a relic now, but it's still fun. The making-of documentary on the 2-disc special edition is really interesting, too - it was really the product of a tiny animation company and a lot of the stuff was just being figured out as they were filming the movie - there was a very real danger of them not being able to finish it! It certainly is unique-looking.
