From a business standpoint (Universal wanting something "new" opening at USF prior to Epic), it makes sense that the scope and scale of this overall project is, generally, what it is. I think the "Minion Studios" idea is kind of brilliant, because it turns some of the architectural limitations of the area into features, not bugs. Short of that, I think painting some stylized city skylines on both the Minion Mayhem and VillainCon soundstages would have at least broken up the feeling of them just being huge beige boxes a little bit. Any extra effort to do that, I'd appreciate... because the theme of the land is no longer supporting them just being soundstages (which Production Central still, basically, allowed for).
For my personal preference, I would have rather been made to wait until 2026 (or whenever) if it meant overhauling the entrance of the park, fully demolishing the Hitchcock/Shrek building, and putting a purpose-built ride on that space (in the vein of Hollywood's SLOP, perhaps Minion-themed if not a one-to-one clone).
But it is what it is!
