Black Mirror: parents' guide

Often graphic and bloody: stabbings, shootings, a saw dismemberment, a severed head, and torture of digital clones. A baby and other children are murdered in different episodes. Sexual violence: characters are coerced into porn and sex acts, including a forced act with a pig.

Frequent strong profanity in most episodes. Plugged In counted more than 35 f-words in "USS Callister" and about 34 in "Joan Is Awful," plus s-words, "bitch," crude terms for genitals and misuse of God's name.

Varies by episode but often frank: simulated sex with partial nudity, a 15-year-old's first sexual experience watched by her mother, pornography as a plot point, and a virtual-reality affair. One episode builds to a coerced sex act with an animal, mostly shown through reactions.

Drinking, drunkenness and cigarette smoking appear often. The interactive film "Bandersnatch" makes LSD use a plot point and includes a shared joint, a teen tries cocaine in "Arkangel," and euthanasia drugs feature in some stories.

Many episodes are deeply unsettling: surveillance, torture, killer robot dogs, demonic possession and people trapped in digital worlds, with bleak twist endings. One episode shows racist abuse of a South Asian woman in late-1970s Britain, and child sexual abuse figures in at least two episodes.
