We all know horror movies are meant to be scary. Duh.
But every once in awhile, you'll sit down to watch a seemingly chill, non-horror movie, and it surprisingly scares the SHIT out of you.
Maybe Pan's Labyrinth made you pee your pants, because you were expecting something a bit more lighthearted.
Perhaps you watched Grandpa's Magical Toys growing up, but the characters still scare you as an adult.
