Obsession is one of my absolute favorite movies in a long time, and it would be an undeniably poor business decision to not capitalize on the IP for HHN.
But ... I walked away from that film both in love with it, and totally cemented on not wanting to see it at Horror Nights. The horror and themes involved are pretty personal and intimate, and the scale of the movie is so small-scale (there's really only one "horror movie monster" and like, 7 rooms shown in the whole film) that I just don't think it would work very well. Unless they go really psychological with it, I think it would just land like Orlando's Happy Death Day or even their OG Exorcist house. Just missing the point on both why this movie resonated with people, and what makes a haunt scary and interesting.
The very most I could see is a M3gan-type role in a zone, but even then, I don't know how I'd feel about Nikki being represented in that kinda format. I'm sure it's happened before, probably multiple times with different characters I can't remember, but the metaphors going on with Nikki are just a lot more loaded than most other characters repped at HHN, and she doesn't have the crazy iconic "movie character look" like M3GAN, or the "crazy guy in a mask" mass appeal like Grabber, Jason, Michael, Art, that allow you to disconnect a bit and just react to the scary person, imo.
Merch and photo-op standees feel totally fine to me. I think One Wish Willow's will probably be the most popular item in every Spirit Halloween this year. For some reason though, bringing the IP in other ways just doesn't appeal to me at all.
Honestly, talking about a movie I love as much as I do, and that I had such a personal reaction to as "an IP" leaves a definite sour taste in my mouth, if I'm honest. That's a personal hang-up. I know that. It's probably one I'll have to swallow too, cause I know NBC/U are probably chomping at the bit to capitalize on this in any way they can. I think part of me has been hoping that this movie ends up like a Hereditary or Get Out, where it just exists and everyone agrees it's really good and we just ... let it be haha.
I've also been wrong about this stuff before so :shrug: Maybe I'll totally love the Obsession house or whatever. We'll see what happens.
