Now that I have been visiting Disney forums here and elsewhere for the past 5 years, I have been saturated with the 'knowledge' that is out there from Disney ultra fans. I also now consider myself one of these people. Having said that, I can see a vast expanse following the completion of EE in DAK where not a lot was done to improve WDW as a whole. I kind of liken it to what the hub in the MK turned into - some sort of concrete expanse bereft of any character that exhibited a lack of creativity or creature comforts for the people to take in. It was the scripted place for people to go each night that just handed Iger tons of their money.
I feel that this is changing somewhat. In my opinion thanks goes to UNI. It's amazing what the boy wizard is capable of. I fully expect UNI to be 'roughly' half the size of WDW in the not too distant future: 3 parks, 1 water park, 10000-15000 on site rooms, full transportation system, 2 city walks. That is enough to get the Mouse's attention.
That being said, I love the 7DMT. I think that the AAs on that ride are phenomenal. We hit that ride several times each trip and find it to be a perfect counterbalance for the other mountains in the MK range. Meaning, it is a coaster small enough for my smallest kids to venture on but still something that our entire family enjoys. Second, light poles aside (I hope that they fix those), I love the new hub. I think that it is a beautiful change to that part of the park, and also helps control the crowds much better (I don't fear for my family's safety anymore being in the hub after Wishes ends). Also, what really caught my attention as far as recent additions go was the Festival of Fantasy Parade in MK. That parade is a wonder and you can tell that they really spent money on it. I make certain that we always see it at least once on each trip.
Moving on, I can't wait to experience the new Rivers of Light show in DAK next year, as well as the new version of the Kilimanjaro Night Safaris. DAK park in general has been so improved upon already this past year. The new Harambe Market place and expanded/improved upon Festival of the Lion King has made the village of Harambe itself a true showpiece of an immersive land. And Pandora will be amazing. I have supported that expansion ever since it was announced. The land will be one-of-a-kind, and I can't wait for the boat ride and the simulator.
For DHS, both Toy Story Land and Star Wars Land look very promising. And that is just the beginning for that park in my opinion. I think that WDW is on the right track and will see fantastic improvements in their parks in both theming and rides over the next 5 years leading up to the 50th anniversary in 2021. And yes, I am old enough that I don't need the cautionary WDW tale from those that deem themselves wise in WDW lore. I simply tend to view things through a more positive lens than others do. That is my choice, but time will be the ultimate judge here. We will see soon enough.
