Coraline

Directed by Henry Selick of the Nightmare Before Christmas and based on Neil Gaiman's book, is the scariest 3D stop motion animation I have ever seen. The story follows a young girl named Coraline who finds an alternate reality in which everyone is controlled by her "other mother" and have buttons for eyes. This other world feels like a badass acid trip, and if your looking for something along those lines, I would defiantly recommend Coraline.
