In my opinion:
Spaceship - Downgrade
Seas - Improvement to make it more relevant but the ride has no educational message.
Space - Downgrade
Test Track - Downgrade
Energy - the same
Life - Closed
Land - Improvements but would still like a video for Soarin that shows off the whole planet not just cali
Innoventions - vastly improved
I'll do the same
Spaceship - same, just different, vastly superior post show is the real ending of the ride
Seas - same, better ride, reduction of "history" is missed but not by all, relevancy means more people will explore and learn
Space - Are Horizons fans that nuts to think the ride closed is superior to an open attraction about space?
TT - Same, again, different. Instead of the history and future presentations that used to be all around Epcot they've moved towards the TT model of modern education through entertainment and flash (see MS)
Engery- worse, old, great script and i love the ride, but pop culture gets dated (hey this ride was back when Alex had a mustache!)
Life - worse, closed, can't argue there
Land - VAST improvement. Soarin gives the entertainment and flash that gets people inspired and caring, Living continues it, and Circle of Life is old but continues the conservation message. Better food, layout, front area, and theme.
Innoventions - great improvement, though turn over of some areas from attractions to seating areas is alarming.
