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!
Starry Eyes
Starry Eyes came out in 2014. It's very similar to movies like The Fly and Martyrs in the sense that it is a body horror freak-fest that is both nauseating and interesting at the same time. This movie is about a person who is completely obsessed with becoming famous, and she would do absolutely anything to receive the title of "celebrity."
