Coraline

Coraline is a 2009 kids horror animation directed by Henry Selick. It's based on a book by Neil Gaiman. Supposedly for children, it's very dark and grim. Coraline is about a girl who moves into a house with her workaholic parents and finds a secret passage that leads to a neighbouring house, where perfect copies of her parents live, except they're not the same at all. She thinks they're better than her real parents except they have buttons for eyes. The Other Mother soon wants to sew buttons on Coraline's eyes to keep her there out of "love".
I rate this 7/10 for its creepiness.
Coolest bits: The talking cat.
