Send Help: parents' guide

Bloody and escalating: passengers are sucked from a plane, the leads stab, bite, choke and scalp each other, a boar is stabbed to death, and later two people plunge from a cliff and a man is bludgeoned to death.

Frequent: one count found about 25 f-words and 15 s-words, plus motherf----r, c--k, p---y, a--hole and bitch, about ten misuses of God's name, and middle-finger gestures.

A man's bare backside is shown while he bathes, and a woman wears underwear as a swimsuit and poses suggestively with a breast partly exposed. The two huddle for warmth, and a boss's interview questions carry predatory overtones.

The castaways brew fermented toilet wine and get drunk, and one wakes up hungover. Earlier the heroine drinks a bottle of wine alone, and she describes her late husband's alcoholism and fatal drunk-driving crash.

A terrifying midair decompression and crash, jump scares, gory corpses, and a deadly cat-and-mouse game between two people who may each kill the other. One character is poisoned and another is paralyzed.
