My favorite was
Journey Into Imagination because it had all the things I love about my favorite Disney attractions - a catchy and addictive theme song, "One Little Spark" (written by the Sherman Brothers), an extremely cute and lovable main character in Figment, and plenty of charm, heart, whimsy, and fantasy qualities.
I agree that the current version is not as good as the original, but it is MUCH better than the Figment-free second version, and since the current version still has much more cuteness and whimsy than the typical Epcot attraction, and still has cute-as-a-button Figment singing "One Little Spark", it's actually my favorite ride in current Epcot!
Other original favorites were
The Land, mainly on the strength of the late, great,
Kitchen Kabaret, which was my second favorite in original Epcot. I'm a big fan of the Animatronic musical revue genre, especially when they involve cute anthropomorphized singing animals (or in this case, cute anthropomorphized singing food!)
Also right up there was
The Living Seas, because I LOVE animals and could always spend HOURS enjoying looking at the fish in the main tank and smaller exhibits. The manatees were and still are my favorites! I also really enjoy the dolphin and fish feed presentations.
Perhaps I'm in the minority, but I prefer the pavilion even more, now that it's The Seas With Nemo and Friends. The new ride is my second favorite in current Epcot because it has everything I love about my favorite Disney attractions - cute and lovable animal characters, charm, warmth, humor, heart, and a catchy and addictive theme song in "Big Blue World"!
The core of the pavillion of being able to view the animals in the post-ride area is still there; the educational factor is still there; so IMO having a little whimsy and charm brought to Epcot by way of the new ride balances out things nicely, and is a very welcome addition.
Also, I really miss
Horizons and
World Of Motion, and preferred both to what's there now! I loved the optimism and warmth of Horizons, and how it served as sort of a sequel to the great Carousel Of Progress. I loved World of Motion for it's humor. As has been mentioned, Mark Davis was the master of bringing humor to the attractions, through instantly readable sight gags! If I'm not mistaken, Ward Kimball worked on Motion, as well.
I've always LOVED the awesome dinosaur diorama in
Universe of Energy! My memory of the original is fading, but from what I recall, I actually prefer the current version! My favorite part - the dinos - are still there, but now the rest of the presentation is more humorous and entertaining (for me) without losing the educational component. I seem to recall the original being more "dry" and often feeling like a commercial for the Exxon corporation!
