I enjoyed reading your all's thoughts on this. Having gone on it in the last month, I too noticed the horrible condition of the seats- just terrible! Besides that, they are actually very comfortable though. I still enjoy it. It's something good to do after you've done a few thrill rides and you need to wind down for a little bit. When I went on it last- the other people in the theater seemed to enjoy it- attentively watching the whole time (not looking at their phones), and even laughing at some of the funny moments. I really like the voice performances- it has that classic Disney feel. Its presence in Tomorrowland is necessary to keep a sense of originality with Walt's presence in the park and his spirit of futurism.
And harping upon some of your thoughts in previous comments:
-I think it would be Awesome to have a Walt Disney animatronic at the beginning! They could simply use real audio from one of his talks on the CoP. Or, even just one of the videos of him explaining the CoP- either would add a personal factor to it that would make it much more engaging and give greater understanding of its significance and purpose.
-I almost wonder if this will get the "Walt Disney's Enchanted Tiki Room Treatment" where they would forego any flashy modern update and return it to the original 1964 version as a tribute to Walt Disney. Yes, it would change to a solely retro view of the future from that era and through the eyes of Walt Disney, but it would be an authentic tribute that they wouldn't have worry about updating. And in this case they could remake Horizons in Epcot to cover the present day and future portions!!!
-But probably the best thing would be to update it and make it relevant to today, with a properly updated modern scene- I like the idea of what mikejs78 suggested of having the years spaced out such as 1900, 1940, 1980, and 2020.
-Also, regarding the animatronics- I don't think the current ones are bad enough to detract to the performance or anything. Sure, making them much more realistic would enhance the show, but to me, they fulfill their function just fine and aren't a glaring issue.
