17. The Taking of Deborah Logan (2014)

In The Taking of Deborah Logan, a group of students film a documentary about an elderly woman with Alzheimer’s and her daughter Sarah (Anne Ramsay). However, Deborah’s (Jill Larson) increasingly odd behaviors—lashing out in anger, speaking in different languages, and lamenting about snakes and other occult happenings—combined with the transformation of her bony, ragged appearance, lead them to question whether there is something supernatural at play beyond the mind-altering illness.

Aging is a classic horror movie trope, but this movie doesn’t explore it as sensitively as Relic or even X. The quavering camera adds to the suspense and unpredictability, leaving viewers uncertain of where she might appear or what strange new behavior she’ll exhibit. Jill Larson delivers a phenomenal performance as someone gradually transforming into a feral shell of her former self. Her sharp eyes bore into your soul during several uncomfortable close-ups.
