Dang, you must really hate absolutely everything that's IP based at both companies parks that recreate what we see in movies. GMR is probably at the tippy top of that list.
I never said one style was worse than the other. Universal recreates world's from IPs. Disney creates world's IPs can live.
At Universal you visit Hogwarts. At Disney you'll visit a new planet in the Star Wars universe where these characters and stories can happen or live. Its different styles of theming. Different goals. Even Pandora has a while new plot and has (as far as I can tell) no direct recreations of places from the movies. It's a new take on the world, not just the world itself.
GMR is literally meant to be a tour through movies and none of the segments are meant to be taken as real. If you look at the ceilings in that ride it is all soundstage ceilings. You're never in OZ, you're taking tour through the movie itself. The difference is in the framing device.
Disney has no lands that are complete recreations of movies. Individual rides, but not whole lands. And those rides (with some exceptions *cough* Frozen *cough*) fit the themes of these lands. Universal has few lands that aren't direct recreations. I love both in different ways, but I personally don't think Uni's style has the same heart as Disney's. I love Potter land as I'm a huge Potter fan, but I never feel that immersed when Dragon challenge is fourth year, Gringotts is 7th year, and Forbidden journey is neither (Harry's hair is cut and Dumble is alive). But every vudual detail is correct in the land. They did a fantastic job recreating the castle, Hogsmede, (I haven't been able to go yet, but I assume) Diagon alley, Hagrids Hut, etc. But to me, the inconsistent timeline and prioritising more recognizable moments/objects over making it feel like a real breathing place makes it feel like it has less heart then most Disney lands. Why is there a wanted poster for Sirius Black? Are we in the third year? Or is the Sirius Black poster just a recognizable element from a film ao they included it even though it didnt make sense. The Very Potter musical was more consistent with the timeline. BUT I enjoy Uni for having exceptional rides and showing me all the sets and props I could ask for. It may hurt the immersion a bit how staged it feels and how many recreations of items from the movies they include even when they dont make sense, but I love getting to see everything. I love the golden egg, the flying car, the Sirius Black poster, the Maruaders map, all of it. I even waited over an hour in the hot sun to watch someone else choose their wand at Olivanders. Forbidden Journey is incredible (even if it makes no sense timeline wise). I love Dragon Challenge even though the ride itself is entirely unthemed. I even enjoyed Flight of the Hyppogriph and seeing a glimpse of Buckbeak.
Disney does have the same problems too sometimes. Star Tours is a mess timeline wise, but I enjoy that ride on its own the same way I enjoy Uni rides. While I wouldn't say they are as atrocious as some would, the Magic Carpets don't fit between Tiki Room and jungle Cruise. I'd argue that Adventureland is already a hodgepodge of locations mashed intro a general land where adventures live and thus Aladdins adventure can fit, but it isn't blended in well with the rest of the land.
BUT in General Disney creates places characters can live. Universal recreates where the characters already live. Both have merits.
Though, like I said, I do prefer Disney's style. That's why I'm on a Disney fan site. I'll take new worlds over highlight reels any day.
I've gathered you prefer Universals style in most regards and that's ok. Opinions come into play here. I just see immersion as different between the two parks. Immersion at Disney is creating new lands. Immersion at Uni is recreating lands.
