Yeah, see, for me, it's being put into the middle of a movie scene that I find the most unappealing. If the story has been told right, then I should have felt that when I watched the movie. When I walk through a house, I want to see and experience something new. A house shouldn't need a tie-in to make it memorable, imo. If it does, then the creative force behind the house, I feel, has failed.
And I'm not coming down on all IP houses as bad, or saying that people who like them are wrong. Just do something unique with them. If you're going to do Walking Dead, give me original characters and settings. Put it in a different city, for example. And as on the fence as I am about the Alice Cooper house, I commend the fact that it's using the IP as inspiration, but then doing its own thing. I hope that Silent Hill follows suit. Honestly, I think that's the best way to utilize IP's in a setting like this. It gives you the ability to capitalize on marketing (as was mentioned earlier) and bring in some familiar iconography, while also giving attendees something new. And it doesn't tie A&D's hands in what they can create.
It's also something that the parks already do with their normal attractions. Jurassic Park, MiB, The Simpsons, Spider-Man, and the others all throw you into their respective worlds, but then give you a new adventure. You're not just living an episode of The Simpsons you saw on Fox last week, or riding along with J and K while they fight Edgar. Jurassic Park, while loosely following the same story beats, puts you in a setting that wasn't in the film and then branches from there. If IP's are going to be used in HHN, then that's what I want. It's a way to be original within the confines of an established universe.
