Siren (2018) Parents Guide: Is the series OK for kids?

This season delves into polyamorous relationships, with Ben, Maddie, and Ryn sharing intimate moments including kissing and implied sexual encounters without graphic nudity. Mermaid mating rituals are a significant plot point, depicted through intense vocalizations and suggestive body language. There are also instances of shirtless men and brief, non-graphic depictions of partial nudity (side butt). Sexual tension and innuendo are present in various interactions.

Violence in Season 2 is more frequent and often includes mermaid aggression, such as attacks against humans or other mermaids, which can be bloody but not overly graphic. There are scenes of physical altercations, armed confrontations with military personnel, and peril involving environmental disasters like an oil rig explosion. Deaths occur, sometimes showing injuries or aftermath in a moderate way.

Mild language is used infrequently, including words like "damn" and "hell." Stronger profanity is rare, keeping the language generally moderate despite the intense situations.

The season explores themes of colonialism, exploitation, and cultural clashes as humans and mermaids struggle to coexist. Moral dilemmas surrounding the protection of an endangered species versus human self-interest are central. Grief, betrayal, and questions of identity, especially for mermaids trying to adapt to human society, are recurring. Medical experimentation on sentient beings is also a strong theme.
