The Sinner (2017)

The show adapts the novel "The Sinner," where the lead detective is a woman (Commissioner Rudolf). In the series, this central role is portrayed by a male character, Detective Harry Ambrose, constituting a gender swap for a key figure from the source material.

The film portrays a specific, extreme interpretation of Christianity (Catholicism) as a source of severe psychological trauma, guilt, and abuse for the protagonist. Her mother's rigid, judgmental faith directly contributes to Cora's repressed memories and mental health issues, with no significant counterbalancing positive portrayal of the faith itself.
