I can honestly say that for the most part I disagree with nearly everyone
I mean I would agree that Stitch for AE is the worst on the list, but even that one I am not kicking myself over. AE, in my opinion, was out of place in Magic Kingdom and the number of complaints that attraction had cripples the amount of complaints people have over Stitch (trust me).
Obviously the Soarin' and Test Track changes were upgrades, most agree with that ... M:S for Horizons? I am not nor was I a Horizons fan, so maybe that's where the indifference lies.
The Nemo overlay in The Living Seas and the Mexico Pavillion overlay are the ones that make me chuckle ... The Living Seas was lamented for years for being "Disney's 'hasty pavillion response' to Sea World" and here they put effort into it and people still complain ... Mexico sees so much more foot traffic, but they somehow 'sold out.' But in comparison to the original plans for EPCOT, wasn't EPCOT '82 even a sell out :lookaroun?
And finally (to wrap up this entirely unnecessary rant), while I would be happy, thrilled even, to see that 20k spot being filled, I do not miss 20k, found it to be incredibly lame, even for its time, and no upgrade in the world could have justified such prime MK space. Now, I agree it's obviously a downgrade due to the "nothingness" that resides there now, but still, not a travesty.
So I guess I am one of the very few lucky ones who didn't have much of a connection with any attraction that has ever been replaced :shrug:
