An all-ages Scooby Doo dark ride would fix that…
I know you keep bringing up wanting Scooby and Beetlejuice for Dark Universe, but I genuinely don't think either would fit this land at all.
DU is not just USF/USH-style spooky land. Darkmoor has its' own individual vibe and world-building based narrowly around specific parts of the UCM franchise.
I'm not usually a stickler for world and timelines getting in the way of fun - I want Galaxy's Edge to offer both Anakin
and Rey era experiences, and it
is fun to see those three spooky IP hanging around at USH - but I think seeing USF-type Beetlejuice or Velma in the current iteration of Darkmoor would pretty instantly crack the very purposeful design that went into making what's essentially an original world for Epic Universe, one with relatively dark and grim tones.
There's a reason just about every UCM character got a huge redesign for the new land, plus new adapted shared backstories. Classic Gillman would not fit the vibe of Monsters Unchained, so they had to adapt them a bit; and same with the rest. The hope would be that Beetlejuice or the Mystery Gang would be Darkmoor-ified, and who knows how much and for how long WB would be game for that.
I just don't necessarily think that anything the UCM can do, means it
should happen in Darkmoor. I think seeing Dracula and Victoria dancing to the Monster Mash would give a lot more
Star Wars Weekends camp than
Galaxy's Edge prestige. The latter is pretty clearly the vibe Darkmoor is trying to go for. We're working off the Potter template here. High standards all around.
