Nemo is great.... if you are under 10.
The imagination pavilion is a thematic mess (I hope Inside Out finds a way to resurrect is... yes, I might be willing to sacrifice Figment if they make the pavilion great again).
The Land is a solid pavilion, could use a little plusing.
UoE needs a modernizaton, but can still be great if given some love.
"Tron Track" is solid.
Mission: Space is solid.
SSE is solid... until the end.
The World Showcase is fun to walk, nothing really to complain about there other than it would be nice is they added a few things to the existing pavilions (and not change Norway).
Give EPCOT Center $500m and I think it's near the top of US Disney Parks.
