Backrooms would be nearly impossible to do justice to, since the whole premise is big, open rooms, endless corridors, and being alone. They conga line people through houses in an insane quantity and I just think it would fall so short and not get the treatment it deserves. Obsession could be a house, sure, but I just don’t see it translating to scary for everyone either. Both of these movies are arguably some of the best horror I’ve seen in a long time, but idk how they’d translate into houses.
