But IOA also has Seuss and Lost Continent, which are free of these thematic flaws, unless you count RockIt sticking up above Seuss and the Poseidon's Fury show building being visible from Port of Entry. The backstage views of Port of Entry, are like you mentioned, really only visible from on ride the Hulk. This is bad, I will admit. I actually just look the other way cause it bothers me. I did watch an on ride video of California Screamin', and while on the entire ride you get some pretty bad backstage views, even towards the very end of the ride. I guess both Disney and a Universal get lazy when hiding backstage views on their larger coasters? Haha.
Jurassic Park in IOA has certainly been marred by the FJ show building and Universal's attempt to jam as many stalls and food stands and games as possible into the large island. There is either a tattoo, hair braiding stall or snack stand every five feet. Jurassic Park has certainly lost much of its luster, as it used to be so much more mysterious. Camp Jurassic and Discovery Center are still amazing though, and as long as the John Williams' score swells through the land, I'll at least be happy.
Sorry for the tangent, haha.
