I enjoyed Horizons, but the first time I rode it I felt it was terribly outdated.
It talked about "in the future things will be done..." for things that already were here today. And some things that just plain were not going to happen as predicted.
If the ride had not been closed it would have had to go through a conceptual overhaul to actually be what it intended to be -- that is a glimpse of life in the near future -- just over the Horizon so to speak.
I miss the ride, but for purely nostalgic purposes. I do hope that the mission to space ride in the space pavillion will be a learning ride.
I hate to think of Epcot moving away from these things that help make it stand apart from other theme parks which tend to cater to thrill ride seekers.
Thrill rides have their place, I like them.. but not at Epcot. I would much prefer more educational and informative "dark rides" like Horizons, and Spaceship Earth.. and Living with the Land.
If I want more roller coasters, I can go to Universal (which did not impress me) or to Six Flags etc.
Sorry to rant, but the "carnivalization" of WDW is really beginning to rile me... I think Walt is turning over in his grave (or in his cryogenic chamber or urn or wherever his body may be)
