I really think they should make some of these spaces modular, so when IPs fall out of the spotlight, they can easily change to a new one. Some IPs are timeless (Potter will be, Seuss, Simpsons, Marvel (although they were almost dead in the 1990s)), but there are some, in my opinion, like Shrek that could be revived easily with a new theme. Same for Barney and some other areas (Nintendo is timeless if it does indeed move in there). One of my fears is they will decide Mummy is no longer cool enough and will raze it for a new screen ride. I don't care if they re-skin it, but leave the coaster alone!
