For the polarizing one, I think it’s Crypt TV. Some people are going to love that it’s getting house love, others are going to hate that it’s back considering the “failure” of last year’s street. For the record, I imagine that the stationary nature of the characters would make for a really great house, which is why the street was particularly bad.
As for “Meta”, I think it’ll likely be something LIKE having Jurassic World Dominion at the event. While I haven’t seen the most recent ones (and imagine the actual theme park has been vacated/trashed/etc), maybe Jurassic World, or an in-universe haunt, is putting on a Horror Nights-style event, when all of a sudden the dinosaurs arrive and begin to kill patrons. They re-use some of the screens from the Jurassic World ride in California. On the map, they call the maze Jurassic World Domination: Extinction. In the “in-world” haunt of the maze they call the house “JW Domination”.
Or, like, an in-story haunted house in Carey, OH has been given the “Purge” treatment - like, each room is designed specifically to reflect an IP they don’t have but then they “purge” each of the rooms.
