The Thing
Directed by John Carpenter, this science fiction flick is sure to scare you away from any artic encounters. When a team of scientists finds a “thing” that can shape-shift into the victim's bodies, anyone could be the monster at any time. Believe it or not, for a movie that was made in 1984, this one hits just as hard as the topical modern films that are coming out now.
The Taking of Deborah Logan
There are hundreds of movies about demonic possession that you would never flinch at if you're a horror fanatic. This one, on the other hand, is borderline deathly terrifying. The Taking of Deborah Logan is a mockumentary about a woman who is struggling with Alzheimer's, but it turns out she's just possessed instead.
