Legitimately, the aesthetic vibe I’ve gotten from the (more accurate) rumor of this is house is pretty Catacombs-esque: dark, simple, windy, and focused on scares. If the cast accepts how important their own intensity is, it has the potential to be a terrifying experience.
(And the “city” confusion was based on how built out the opening graveyard/funeral scene is. So, at the very least, the facade should be pretty impressive.)
