I don't disagree with the overall message of your post regarding stagnation, but I had to single a few things out.
Are you saying it is better than anything Disney has done or just their water parks? Because it's not even better than Typhoon Lagoon. Okay, the slides are, but the wave pool sure isn't, and as a complete, immersive, thematic experience it absolutely is not. In that regard, it lands somewhere between SeaWorld's Aquatica and Typhoon Lagoon. A bit above Blizzard Beach. It's a good and pretty water park, but no game changer.
Not sure on this one. A "blue sky" concept existing decades prior doesn't mean they were copying those exact plans.
But if we go back further, Universal's use of screens for motion simulation were originally done by Disney with Star Tours. Also I'll give you Ratatouille as being a crappy version of Spider-Man, but Runaway Railway is kind of its own thing and not comparable.
Technically, Disney did Tron before Hagrid's in Shanghai. You're also being strongly dismissive of Rise and Flight of Passage.
Shrek 4D did last almost two decades. But beyond that, we don't really know this as truly bad attractions weren't by Universal until the last decade.
The point I'm trying to make is if you single out one company as doing everything good and the other doing everything bad, you end up with a bunch of contradictions.
The volcano bay mention was becuase in big industry changes it was not mentoned at all and it is something that resort was building, so it seems weird not to mention an entire large waterpark getting built. Improving the water park experience of not waiting on slides and interactivity is what it did for industry. Guests really enjoy that. No one had done virtual queue included with the water park concept before and it actually works better there than at theme parks becuase you lazy river or do other things until it is time to go. You never wait as long on hot stairs is the biggest innovation with Tapu Tapu (although The food is far better than any other water park in FL, which is odd, as Uni gets trashed on for quick service)
I was not trying to be dismissive of the other things. I was just pointing out trends and how they go. The only real issue with Disney is their stagnation and avoidance of trusting their Imagineering with in house IP.
Both have had great attractions and meh ones. I agree with your final statement.
And they did not copy exact plans for Rise of the Resistance to be Spidey when it was in the works as Superman, but there is a reason they got Scott Trowbridge who is connected to the patents legally for the technology. ;-)
What we do know is as a whole, even with Fast and Fallon being really let downs or step backwards is that for guest pleasing and investment timing, it is working better for Universal now.
Universal Studios has had meh years from late 2015 to now in terms of attractions.
IOA has had some setbacks with closing and budget cuts, but design of new rides and offerings in that timeline is not one of them.
Disney has had EPCOT with those years 2006 to Guardians with nothing new for EPCOT except a Test Track retheme and media updates as Wonders of Life completely shuttered. The sudden Moana, Guardians and Rat were too little too late. I think that is far more egregious than meh attractions(that still please plenty) from 2015-2022 but that is just me.
During those same EPCOT years, Hollywood Studios was pretty darn dry as well. Toy Story Midway Mania in 2008, Star Tours in 2011 and then...a long time before Mickey and Minnie, TS/Galaxy's Edge with a lot of venues closing up doors and neglect.
Animal Kingdom post Everest...I mean enough said because it was pretty dry until Avatar and has been very dry since.
Disney is a larger company with larger resources. So it is wild that we are even able to compare them like this, but Universal did more with their two parks turning into two with a revitalized water park concept in the last fifteen years,
than Disney did with their 4 theme parks and mega sized resort property.
The Mature product Bob Iger pushed when he first got in did not hold as he spent 2 billion on the data resources, and the attendance and guest spending after stagnation has suffered a lot.
This all being said, I imagine the perspectives of the earlier screens suffer a lot on Kong and some on the main, as well as the outdoor portion should definitely come back.
