When Evil Lurks: parents' guide

Shocking and graphic: heads bludgeoned, an axe murder followed by the killer hacking at her own face, people run down by vehicles, a child's remains being eaten, intestines and severed body parts. A goat and a dog are shot.

Subtitled strong language including f-words and motherf-er, plus a--hole, bastard, damn and hell. Common Sense rates the profanity as heavy, and the UK censor notes the f-word used in a sexual sense.

No sex scenes. A man's bare bottom is briefly seen in a comic, nonsexual moment while he changes, and there are a couple of crude sexual references.

Characters smoke cigarettes, and a woman says she is a little drugged from her sleeping pills. No drunkenness or illegal drug use.

Sustained, merciless terror in which no one, including small children, is safe: a bloated man oozing pus, children with bloody mouths, sudden attacks and a hopeless ending. The demon cruelly calls an autistic teen broken.
