Although this haunted (hungry) house story is from 1973, it's not remotely dated (apart from the smoking) and holds up beautifully. A family moves into a beautiful estate home for the summer and the wife becomes obsessed with the home and caring for it, as well as for the old woman who lives there. Meanwhile, things get weirder and weirder for her husband, her child and their aunt.
Did I mention that it is genuinely creepy? Definitely a great follow-up to The Haunting of Hill House.
