From the New World (2012) Parents Guide: Is the series OK for kids?

Sexual content gradually escalates, particularly in the latter half of the season. Early episodes contain some suggestive situations and implied romantic interest among teens. Later, same-sex relationships become a prominent theme, with kissing (including open-mouthed) between male characters and intimate physical contact between female characters, including fondling breasts and implied sex (no nudity shown, but characters are seen naked under covers). A creature discusses bonobos' use of sexual acts to resolve…

Violence is frequent and can be intense, often depicted with psychokinetic powers. Characters use their abilities to inflict harm, resulting in bloody explosions, dismemberment, and burning. Monster rats and humans are frequently killed in combat, sometimes graphically. The stakes are often very high, creating numerous frightening and intense sequences.

Language is generally mild. Characters occasionally use words like 'damn' or 'hell' in moments of stress or frustration. There are no instances of strong profanity.

Substance use is very mild, limited to characters occasionally consuming what appears to be alcohol or sake in social settings. There is no depiction of intoxication or drug use.

This season explores profound and disturbing themes such as genetic manipulation, eugenics, societal control, forced disappearances, identity crisis, and war crimes. Characters grapple with the horrifying history of their world and the moral compromises their society has made. The psychological toll of these revelations and the constant threat of being 'disposed of' for breaking rules creates a pervasive sense of dread and existential horror.
