Common Sense Note
Parents need to know that Case 39 is part of the "killer children" horror subgenre, in which children are shown to be evil and homicidal; it's a psychologically effective and scary idea, but this movie is mainly out for shocks rather than exploring anything deeper. There's lots of violence, including some scenes involving children (in one particularly disturbing sequence, adults push a girl into an oven and light it), as well as other deaths and injuries. Language includes a few uses of "f--k" and "s--t," while sex, drinking, and drugs aren't prevalent.
Sexual
Content
Some flirting between grown-ups.
Violence
Some violence involving children, including a sequence in which two parents push a girl into an oven and light it. She escapes, but the father pushes his boot into her back to stop her. They duct tape her mouth and smash her hand in the oven door. In another sequence, a boy kills his parents with a tire iron, though no actual "contact" is shown; viewers see blood on the walls and pillows. Adults fight: Viewers see a man with a broken jaw, a man gets stabbed in the neck with a fork, and another man falls on the same fork (it impales him in the eye). Also images of a woman on fire, a dog attack, shooting guns, a speeding car (with a child on board), a burning house, scary demons, and several sudden shocks.
Language
A couple of uses of "f--k" and "s--t," plus "hell," "ass," and "oh my God."
Social
Behavior
The movie suggests that evil lurks everywhere, even in the sweetest and most innocent of children. You can't trust anybody or anything, and there's never any attempt to learn anything, to turn things around for the better, or to find hope in the world.
Consumerism
Characters drink Heineken beer in a bar.
Drugs / Tobacco /
Alcohol
Adults drink a beer in a bar, and the main character enjoys a glass of wine at home. The main character also grinds up sleeping pills into a cup of tea to give to the demon child.
