The same way people say wow I went to IOA and Potter was and looked great but unfortunately the rest of the park looked rundown.
Todays time and age wouldn't level of "theming' be dictated by social media in addition to...
Materials used, effects of unintentional aging, spatial area, visual icon, passthrough time, feelings of immersion, crowd flow, overall theming compared to the rest of the park....
Port of Entry biggest issue isn't so much the Port itself, its the materials over time have made it look rather cheap and aged, it lacks any iconic imagery within the park that gets people hyped, the cohesion to the lands next to it is rather lacking as you go from something more realistic to two colorful and cartoony areas, and spatially it can't hold crowds like other theme park entrances can. The icon of the Park isn't even within the park. Same thing with Universal Studios.
Comparing to certain Disney Parks (MK, DL, TDS, SDL), despite some of them being older, they don't look cheap, its a key social media spot with people taking pictures, its cohesive to the areas around it, and they can hold/handle traffic way more easily than IOA.
