Pulse
The internet can be a scary place, but this film takes that concept to a whole new level. In this movie, computers take the place of poltergeists. They can project their own (and the computer owner's) consciousness into the real world. This movie will make you want to hop online after you watch it just to clear your search history.
The Witches
Some horror movies are specifically designed to scare kids, and this is one of them. Witches around the globe change their faces to appear as normal-looking, professional women. However, they use these disguises to trap children in places where they can conduct rituals. Using witch magic, they turn the kids into mice and stomp on them!
