I was thinking this over recently, and I strongly believe that a post-production attraction needs to be put here. USF needs to strongly emphasize the "Studios" in its name. By having several more production attractions, a better connection is established with the studio area, while still keeping a majority of the normal rides. It can't just be a random movie theme park attached to a set of soundstages. It needs to be more than that. USF should overall focus on every aspect of film, from its creation, to its release, and to its effect on culture. The decision to remove Hitchcock next door was too, wrongheaded. However, I am happy that we have Disaster and Horror Make Up for production shows.
Some people say "The public lost interest in production shows". That's just plain false. There's no evidence that Universal put out surveys, and if they did lose interest, this would mean that the production shows at USH, USS, and DHS would be gone as well, and people would be bored during the production parts of Disaster and Horror Make Up, which they aren't. The fact is, even if it can be proved that they did lose interest, it's irrelevant. People never lose interest in anything, only the way it's being executed. Disaster is popular because it's a production show that mixes in ride elements, and Horror Make-Up constantly changes and involves horror effects, things people love. Basically, anything can be made appealing to anyone. The real reason for Hitchcock's closure was that it suffered from lack of improvements to increase revisitability. The fact that it involved production has zip to do with it. Saying "The public lost interest in this and there is no way to make it appealing again to them" is, at best, close-minded thinking.
Universal needs to give the park a coherent feel, and to do that, they need to make the "Studios" aspect one of the main attractions again, along with "Ride the Movies" as they did originally. Plus, as some members here have mentioned before, they need to make the name "Production Central" make more sense again. An attraction of such in this abandoned building should be the first step.
