I wouldn't sleep on Lost Boys. Besides Gremlins (which has its own issues), the best known 80s horror property left to do. Lends itself to a house rather easily, except maybe the boardwalk, but Us made that work. Done right could attract the thirsty Eddie fans -- vampire sax player would have multiple Twitter tribute accounts. And owned by WB, who are probably open to playing ball again after their own haunt failed.
I think because of Beetlejuice, WB is open to working with Universal Orlando.
The bigger question I have is if WB is open to working with Universal Studios Hollywood after the Beetlejuice situation. If they are not open to working with Hollywood, maybe we could start seeing more exclusive IPs to Orlando only.
