Creepiest Movie Children - Rotten Tomatoes
The Shining (1980)

Danny Torrance seems like an average kid. But consider this: he was once beaten by his alcoholic father, and now he's spending the winter at an isolated hotel with emergent psychic powers. Not so surprising he's a bit bonkers, is it? At the Overlook Hotel, Danny has gory visions of past murders (bonus creepy kids: bloody twins!), encounters a vengeful old woman/spirit, and speaks in a raspy voice while calling himself Tony. "Redrum," you say? Um, yeah, we'll pass on the babysitting gig.
