I would tend to disagree, but to each their own. While I would like some changes in Future World and/or more countries added, I don't think Epcot is lacking the way that DHS is. DAK needs more attractions and Pandora will hopefully answer that, but DHS is the park most in need of a re-imagining and expansion. DHS has some of the best all around attractions, but is just a mess thematically and has far too little to do.
I can understand, and I agree that while Disney Hollywood Studios has a decent selection of attractions, it's still one giant thematic mess. Once the working studio gimmick disappeared, Disney hasn't done a very good job in rectifying or upgrading the park at all and is in desperate need for some love and quite possibly a re-purposing of what it currently is, very much like what recently happened with Disney California Adeventure.
The sloppy theming aside, though, I'm probably one of few here who could spend an entire day at Disney Hollywood Studios. I visit and experience a number of attractions there (Tower of Terror, Rock n Roller Coaster, Star Tours, Toy Story Mania, Muppet Vision 3D... even Beauty and the Beast, Voyage of The Little Mermaid, The Great Movie Ride, and Lights, Motors, Action
). TBQH, if the theming was executed much differently, it would probably be my favorite of the four parks, but just as you said, to each their own.
In my opinion (emphasis on
my opinion, as I know many people on here don't feel the same way), Epcot has sort of the reverse problem. Thematically it's a great park, but doesn't have a lot to do. I go on Spaceship Earth, Ellen's Energy Adventure (as it does hold a special place in my heart, honestly), The Seas with Nemo and Friends, and depending on the wait time, Test Track. I normally don't get a chance to ride Soarin' because FastPasses are either unavailable for the day or the standby line is ridiculously long, I don't particularly like the rest of the attractions in The Land, and needless to say I bypass Imagination completely. Also, call me a whimp but I just don't trust Mission: Space, whether it's orange or green.
While I do like to maybe walk around World Showcase every once in a while and have a nice dinner in France or Mexico, this section of the park isn't really my cup of tea. If I happen to be visiting during the Flower & Garden Festival, then I'd invest more time into walking around World Showcase, but otherwise I peruse this section of the park because it's what my parents like to do.
I feel that while Epcot may be strong in the one half of the park dedicated to different countries (which a lot of people love, and I can totally dig and understand that), it's lacking quite a bit in the other half dedicated to edutainment. If they were to put some imagination back into Imagination and re-purpose Wonders of Life, I think that would be a substantial amount of improvement and give young whippersnappers like myself a lot more to do. While the new and (hopefully) improved Test Track might help out for a little while, I think it's time for some bigger changes to this half of the park.
I'm not hating on Epcot at all, I just think it has a lot of unused potential, especially since it's such a classic and beloved theme park to many of us.
