Every single pavilion is lesser now than it once was. The Land is perhaps the best example of what happened to EPCOT as a whole. Because like EPCOT at first glance it looks like it is still there, and it all functions pretty well. The Land nowadays is great. Good rides, good restaurants, pleasant atmosphere.
But look at the picture below. Spot the differences.
A fountain. And an artistic one at that.
Carpets.
Murals on the sidewalls.
Handpainted ceiling instead of a few pieces of cloth.
Balloons that move up and down.
Balloons that are tied to the larger ideas behind the pavilion.
