I think many people have skipped over the part of not using IP correctly.
Like I stated in the original post... Nemo was executed very well. It could go a step further by imitating the aquarium in the sequel... And by making the ride a bit better.
Frozen Ever After was not executed very well. It replaced an attraction that was unique and fitting for Epcot while being true to the country it resides in. Frozen is just another Magic Kingdom attraction that should have gone in magic kingdom... Or just make a frozen land in HS since that is where HS is going these days.
The Lion King was well executed for its environmental film that used to be in the land.
Rat feels like a studios attraction (ironically being copied from an overseas studios park), but is not as controversial because it didn't replace anything and was essentially shoved out of site in the back corner of the park.
Beauty & the Beast sing-along is the biggest evidence of how messed up Disney is treating Epcot. Which I hope everyone can agree upon that.
Guardians just flat out doesn't work and completely ruined the aesthetic of the park on that side with a big ugly box. Guardians is one of those "at least it KIND of works" arguments...
An example of IP working to fit a park's overall purpose that is NOT in magic kingdom... Original Hollywood Studios. Never seen so much IP in my life! Great Movie Ride in and of itself had a ridiculous amount of IP! Muppets showcasing their 3D technology. Indiana Jones being used to showcase how stunt films were made. Even Rockin Roller Coaster worked to the theme of a band doing a tour in Hollywood as a big record label. If they weren't showing how films were made, they blended it in with the rest of the park such as Tower of Terror, or Star Tours queue looking like a movie set...
Animal Kingdom, for instance...... Bugs Life is a great example of using IP to present a parks message, with it explaining to guests how important bugs are in the animal world too. Joe Rhode made it possible for Avatarland to actually work in AK by showing us how nature will always take back what was once there, the possibilities of life on other planets, and the thrill of discovering new worlds. That, in and of itself, is it's own beastly kingdom.
Chester & Hester was a mistake, but if you looked at the original plans for dinoland, you'd see that the excavation sight and everything planned for that space would have given us insight on how we deal with fossils, and dinosaur in and of itself literally takes us back in time during one of the biggest natural events on earth.
...Epcot??? Frozen, plop it down. No thematic reasoning. Rat, plop it down. No thematic reasoning (other than France.) Guardians, plop it down. No thematic reasoning. Wreck it Ralph meet n greet in Imagination, plop it down. No thematic reasoning. Moana, plop it down. No thematic reasoning.
At least I can find a reason for Nemo being in Living Seas... Heck... It would make even more sense to build a new living seas in AK and just put that next to the nemo theater and have an aquatics section of the park... But alas... It's fine...
The whole meaning behind Moana's water exhibit could have easily been done with a new water exhibit outside of imagination. It was unnecessary. We have up better projects for this.
Even what COULD have happened... PLAY! Pavilion. Plop as many IPs down in world discovery inside one building as possible... No thematic sense.
At least things are starting to make sense in Hollywood Studios. As mentioned before, it's slowly migrating into an islands of adventure style park with fully immersive land. "step inside the movies" park. SLOWLY... but surely.
Epcot? A mess mess mess.
