Spoilers for The Haunting of Hill House follow.
The house is a textbook definition of a haunted mansion. Drafty with long, dark hallways, dank basements, a dumb waiter, a sealed-off room, and ancient furniture, the structure appears — as Shirley Jackson described it in her 1959 novel The Haunting of Hill House — as “a house arrogant and hating, never off guard.” Slightly off-center, with right angles that are a “fraction of a degree off in one direction or another,” Hill House could be described as the embodiment of evil.
Meanwhile, the young Crain family, the Hill House occupants from last year’s hit Netflix adaptation, are at the mercy of horrifying phenomena that haunts them, both during their time in the building, and for years after as ghosts seek to lure them back.
