It's what the ride is made out of itself, the screens and the motions together that causes motion sickness for some they can handle a few and others it's one ride and that's it.
The repetitiveness is where people complain because it's "new" (because new doesn't always mean new, it can and often means replacement) ride after ride after ride of the same thing. It's what got on people's nerves with Universal. Mickey and Minnie is still a box (well you're sitting down in the same type of thing as some of the rides you mentioned), Smuggler's Run is still a box although you're in spaceship like seats, Remy is still a box (sure the way the trackless part is cool). Box in this context is just a ride vehicle that moves you but you're being moved for the purpose of starting at screens or you're being jerked around but with screens (smuggler's run jerks you around for instance well it's bumpy lol).
So when you see Disney having a lot of their "new" rides that have a lot of screens in them where the ride relies on those to immerse the guest it's basically what Universal was doing.
Because being bad is subjective. That's not what I'm at least meaning. FOP is a great ride, Fast and Furious isn't but both rely on screens. I don't care that FOP is technically amazing and Fast and Furious is..well IDK how to describe it lol. What they share is that they are both screen based. As is Remy, Mickey and Minnie, Guardians, etc Disney did not used to be like that with a lot of their rides.
Don't get me wrong I like some of these rides but if Universal can take the criticism for years it's now time for Disney to.
