The House That Horror Built follows Harry Adams, a single mom and horror movie fan, who takes a cleaning job at the creepy mansion of the reclusive director Javier Castillo. His home, packed with eerie props and trophies, has an unsettling vibe right from the start. As Harry explores the mansion, filled with reminders of Castillo’s violent film legacy, strange things begin happening—mysterious noises, costumes that seem almost alive, and other unsettling moments.
The mansion itself almost steals the show. Filled with film set props, costumes, and puppets, the mansion is claustrophobic, richly detailed, and dripping with tension. Harry, meanwhile, comes off as vulnerable and also pretty passive. She mostly reacts to what’s happening instead of driving the story forward, which can be a bit frustrating. Plus, she has this habit of spiraling into worst-case scenarios—her son even jokes she imagines “every possible permutation of doom.” You’d think with all that anxiety, she’d be a little more suspicious of the things that are happening.
Christina Henry’s real talent shines in building a spooky mood. The creepy house, the mysterious director, the whispered voices, and ghostly hints—they’re all here. But the tension unfolds way too slowly, and the pacing drags. Even when the story finally picks up, it’s more melancholy than thrilling. The House That Horror Built might appeal to fans who enjoy slow-burning thrillers, but if you’re after chills, jump scares, or fast-paced action, this one’s more like wandering down a dim hallway that never quite leads to a real fright.
