I absolutely do not understand the idea that USF obviously needs work more than IOA. IOA has an entire land shuttered and almost no live entertainment whatsoever plus several lesser but still very significant problems (a headliner ride running without a third of its content, a busted Seuss entrance arch with no effort to fix it, a land that is so unable to handle its crowds it routinely becomes inaccessible, etc). Studios, in comparison, feels a complete park with a pretty good entertainment lineup and a slightly lackluster slate of rides. Of the two, IOA feels much more “broken” to me.
If Studios DOES need work to improve its ride lineup, and I agree that at some point it does, that’s a significant indictment of the recent decisions regarding the park. Studios recently had (or is having) two major additions - one in the most prominent location in the entire park, one replacing an entire land that has been sorely in need of reimagining for many years and could have hosted an area on the level of Diagon. The fact that improving the Studios lineup still feels like an emergency to many shows how significant a mistake it was to go so cheap on both additions. Had they been what they should have been, the Studios would be nicely situated for several years.
Even with those additions, however, Studios seems to me to be in a better place then IoA.
