Happy Death Day: parents' guide

The heroine is stabbed, bludgeoned and killed repeatedly by a masked killer; others are hit with bats and pipes, run over, poisoned or thrown from a window. Blood shows on knives and in brief spatters, but most stabbings happen off-screen.

One f-word and about a dozen s-words, with frequent 'bitch,' 'slut,' 'whore' and 'asshole,' a crude word for female anatomy, roughly a dozen misuses of God's name, and one obscene hand gesture.

Constant crude jokes about hookups, genitals and masturbation. The heroine has an affair with a married professor (kissing only), wakes in strangers' beds, and walks naked across campus with only her back shown. A male student cues up porn showing two men kissing.

College partying: she wakes up hungover after a drunken night, students drink at a party, and a dorm room holds a large bong. She tells a police officer she is drunk and high so he will arrest her.

A baby-masked killer stalks her through a dark tunnel, a hospital and her dorm, with jump scares and chases. She hangs herself in one loop to undo a friend's death, and quieter scenes deal with grief over her mother.
