The World that intrigues me the most is the one the Universal monsters will end up in. If it were up to me, it would be a Spooky World featuring not just the monsters but also Beetlejuice, Scooby Doo and heck why not throw the Ghostbusters in there.
What I really want is Universal's answer to the Haunted Mansion. I could imagine a trip through the Deetz's house complete with after-life and model town. Or a Scooby Doo haunted house. Or Dracula's castle featuring all the classic monsters. Basically I want a family-friendly dark ride with a creepy tone similar to the Mansion and of equal scope.
If the Ghostbusters show up, I could see doing something Toy Story Mania-ish. But of all the different properties that could end up here, that's the one I am least interested in.
The possibilities for Scooby are just limitless. If Universal is looking for a kids' area, Scooby Dooby Doo it up.
If Beetlejuice doesn't get a ride of his own, I hear he has experience with stage shows.
I wouldn't mind a Tower of Terror ripoff if it was done with an equal level of showmanship. If it's just Dr. Doom all over again, no thanks.
Nintendo? DreamWorks? Fantastic Beasts? That stuff's all okay I guess but I want the monsters!
