I'm significantly underwhelmed by most of the work put into Epcot over the last decade*, but because the park still has things that mean a lot to me (Spaceship Earth, Living with the Land, The American Adventure, the World Showcase films, World Showcase in general), it's still a must-do during every trip.
Which means I'm part of the problem.
* There are aspects I like (the new entry, the Beacons of Magic lights/shows on Spaceship Earth, the new center of the park, the area around Ratatouille).
