Most of the users on the General Discussion board, from what I've observed, as well as most Disney history types.
The main problem with Ellen's Energy Adventure, as you've said, is that it is horribly dated. If one was to re-film it, but keep the exact same presentation, you're only kicking the can a bit further down the road. Once you start putting in real-world references like
Jeopardy!, you're practically building an attraction with a timer and people are going to hate it fast.
A perfect example would be the travesty that was
Enchanted Tiki Room Under New Management.
The reason Walt's original Tiki Room show lasted so long was that it was mostly original; with the exceptions of the Hawaiian War Chant and Heigh-Ho, all of the songs were written for the attraction by the Sherman Brothers. This gave the entire attraction a timeless quality.
Under New Management decided to throw in pop music to be more "hip", and we got the birds singing Gloria Estefan. The problem with pop culture is that it's constantly changing...Miami Sound Machine's peak of popularity was in the 80s. They were barely popular in the 90s when UNM opened, and today are virtually unheard of outside of devoted nostalgia-heads who remember how great the 80s were before things went to pot, and the occasional appearance of Gloria Estefan singing at the Republican National Convention.
Back to Ellen's Energy Adventure....
Jeopardy! has had declining popularity since the Ken Jennings Event of 2004.
Ellen DeGeneres' tv show was already waning in popularity when the original EEA was planned (it
dropped from 13th place in ratings to 39th between Season 2 and 3), but it kept going until 1997 with "The Puppy Episode". After that happened, momentous occasion that it was, the tone of the show shifted (instead of being funny, it was more about social awareness) and people started losing interest. A year later, the show was cancelled.
Sure she's popular
now, but popularity is a fickle thing. For the longest time, she wasn't...she had "The Ellen Show", in which she was a high school guidance counselor. It didn't even last a full season; 18 episodes were produced, but only 13 made it to air.
Her forte these days is being a television presenter, either through her talk show or hosting awards shows. Sure, folks love her as Dory, but apart from that, the days of Ellen as an actress are virtually over.
That all being said, if UoE were to become something truly timeless, and utilize that building to its fullest potential...upon closing, it would be something as lovingly remembered as Horizons, World of Motion, or the old Journey Into Imagination.
