Through the Darkness (2022) Parents Guide: Is the series OK for kids?

There is no on-screen sexual activity. However, the motives for many of the murders are sexual in nature and are discussed by the profilers. Several episodes depict the nude bodies of female victims at crime scenes and in photos, but genitalia and breasts are consistently blurred or obscured from view.

Violence and its aftermath are frequent, graphic, and severe. The series focuses on brutal serial murders and repeatedly shows bloody crime scenes with mutilated victims. This includes depictions of stabbings, bludgeoning, and dismemberment, as well as the discovery of victims' bodies. Acts of violence are sometimes shown in brief, intense flashes, and a child's murder is a central plot point. There are also tense foot chases and physical altercations.

Language is mild throughout the series. Subtitled Korean dialogue includes infrequent use of terms like 'bastard,' 'hell,' and 'damn.' Profanity is not a notable feature.

Substance use is mild and consists of occasional social drinking among police colleagues in after-work settings. Characters also smoke cigarettes periodically. It is not central to the plot.

The series is built on severe and intense mature themes. It delves deeply into the psychology of serial killers, with disturbing interview scenes and analysis of their motives and past trauma. A major theme is the immense psychological toll this work takes on the main profiler, who struggles with vicarious trauma. Themes include child murder, sexual assault, misogyny, grief, and systemic issues within law enforcement.
