I see where you're coming from but I think the best thing to do with Hollywood Studios would be to sort of take inspiration from what Universal Studios did with Springfield and Diagon Alley. Immerse people in the worlds of the IP and move away from the studio theme. Disney could easily do this with Pixar, Frozen and Star Wars in Hollywood Studios. To be perfectly honest though I would be fine with anything that involves keeping Maelstrom.
I agree. It should be a celebration of the movies. There's nothing about these IPs that aren't movie-based.
The working studio idea is long-gone and referring to it now in shows generally just endures an eye roll anyway.
