That argument is fine if you want to go debate Guardians of the Galaxy in Epcot. But this is Mickey Mouse in the movie park. It's about as thematically appropriate as it gets.
I'd say "the great movie ride" in the "great movie park" is about as appropriate as it gets. Though I've never been attached to GMR myself, I can see why others would be sad, it's the park icon.
Though you bring up a good point, GotG is as lazy as it gets.
