It Follows: parents' guide

The entity kills a young man while having sex with him in the form of his mother, a sexual assault shown briefly. A mangled corpse, bloody gunshots to the head, a car crash, and a woman drugged with chloroform and bound to a wheelchair.

Strong profanity throughout: one detailed guide counted six to eight f-words and as many s-words, another about 18 crude words in all, plus 'bulls--t' and misuse of God's name.

Sex is central: the lead has several sex scenes with movement and moaning, the entity appears fully nude from the front as both a man and a woman, and teens look at porn magazines and joke about sex.

Teens and young adults drink beer and liquor and smoke cigarettes. One guide reports two teens smoking pot, and the lead handles a bottle of pills; guides disagree on whether she takes one. Nothing is glamorized.

Slow, relentless dread as the entity walks steadily toward its victims in unsettling disguises, including half-dressed and elderly figures. Jump scares, a violent attack at a pool, and an ambiguous ending.
