Our only major amusement park here in Canada, Canada’s Wonderland, underwent the same transformation that you mentioned when Paramount bought it in the 90s, fitting IP everywhere and retheming rides that no one wanted to be changed. I have not been since Cedar Fair bought it, but, from what I’ve heard, it is mostly back to its former, pre-Paramount glory.
You would probably know this as much as I do, but there is at least some beauty with Canada's Wonderland. For starters it is quite close to Cedar Point when it comes to just raw thrills, but pretty much everyone who goes there gets a picture in front of "Wonder Mountain" right in front of the fountain. It is a beautiful shot and thought in the same way as Main Street in front of the castle (although obviously Main Street and Cinderella's Castle are more iconic)
