Three generations of women in an old house, then grandma goes missing and returns with bizarre skin spots and self-mutilative behavior. Conveniently cuts away from all the unexplained stuff, and I thought it was all pretty average until the daughter slipped into a House of Leaves dimension between the walls. Best explanation I could come up with is bodily aging as an inherited disease. Good to watch a creepy horror or two early in the year, it’s unhealthy to save them all till October.
