I think people are in love with the idea of a Backrooms or Obsession house more than the reality of what it'd actually be.
Obsession is pretty clearly playing with themes of consent and coercion, and draws a really uncomfortable parallel to rape/sexual abuse under the illusion of "love." Yes, Horror deals with pretty heavy stuff sometimes, but I think there's a difference between watching that play out in a movie and turning it into something you're supposed to walk through.
Remember, while Nikki is the aggressor for much of the movie, she's not the villain. Bear is... (I'll also allow Ian to take some blame, too). So I don't really know what the house is supposed to be. Are we supposed to be following Nikki while she's being manipulated? Are we just watching scenes play out? The movie wants you to empathize with Nikki, not fear her, so none of those really feel appropriate. The movie works because of those themes, but those same themes are exactly why I don't think it makes for a good haunted house.
I do think they'll want to bring it to HHN, in the form of a photo op, or maybe even some food or merch, but that should be the extent of it.
With Backrooms, I get why people bring it up. The setting is literally a maze.
But the horror of the Backrooms lies in the isolation: being completely alone in the endless liminal spaces, knowing something is there. The fear comes from the feeling of uncertainty while also being alone.
The biggest thing working against that at HHN is... HHN... You're in a conga line. You won't get that feeling of being alone, and without that, I think you lose the thing that makes Backrooms scary in the first place. It's more likely you'll get an original that plays off it to make it better suited for a HHN-style house.
Catching up on the thread and do want to respectfully push back on the Backrooms take, if only because I feel like we’ve seen this exact conversation plays out so many times over the years about whether or not a certain movie would come to the event based on it’s adaptability of horror.
I remember the buzz around Us was certain groups insisting it couldn’t come to the event because the horror aspect of that movie revolved around dopplegangers, and that’s unadaptable for the average guest. Then Us made a bunch of money and they fast-tracked the house for the same year.
Or years of debating whether Terrifier would come to the event over concerns about its controversial nature, that most of the horror was the graphic torture scenes so too passive for a house, etc. Then Terrifier 3 made a boatload of money and it showed up the next year.
Goes on with The Weeknd, The Exorcist, Fortnitemares this year. Are the houses/zones guaranteed to be good? Nope! But if an IP demonstrates that it will move tickets and sell merch, there’s a willingness to get creative with an adaption for the event. Not being the right type of horror hasn't been a barrier.
For Backrooms, the selling point that you get to walk through an recreation of the same practical sets as the movie, in essence step foot into
the actual backrooms, is an incredible sell to the younger audience they’re after. The congaline is a tradeoff I’m pretty sure most are willing to make. Also, there are monsters and people who went crazy trapped in there too, even more if they include Kane Parson’s youtube series. There’s plenty of material for a workable book report adaption.
All that to say, assuming zero issues with rights negotiations and the other usual caveats, I think Backrooms has like an 80% chance of showing up next year, 99% after Backrooms 2 in a few years.
[Obsession, like Get Out, is trickier because the horror material deals with a sensitive team but more importantly, there isn’t enough horror material to adapt outside of maybe a compilation house. With Sinners you can skip over the KKK elements and still have a workable vampire house. Obsession and Get Out leaves you with maybe 20 minutes of material to stretch into a house, just not doable.]
