It is not my favourite theme, but I don't get why Disney seems to have soured so much on the concept of the studio theme park concept that they threw around those weird alternative names for DHS a few years back and are giving WDS this ridiculous new name.
They seem to want to build parks that are full of lands themed around disconnected, film-based IPs. A "studio" seems like the best over-arching theme if you want to do that and have it all cohere in some way. Instead, they seem intent on taking that approach to building parks but ditching not just the studios theme, but any overarching theme whatsoever. What is even weirder in this case is that they are still kind of keeping the studios conceit as the first act of the park which frames it as stepping into a Hollywood studio and the movies. Yet, for some reason, they can't bear to keep "studios" in the name anymore and prefer to rename it to something that sounds like a generic regional park. Even "Adventure" sits weirdly with the combination of IPs they're including.
