The premise, themes of memory, time, and institutional failure, and emotional driver remain traditional crime drama focused on the Purcell case, personal relationships, and Hays's dementia in old age. Casting changes introduce the lead character's portrayal as Black after Mahershala Ali successfully lobbied creator Nic Pizzolatto to recast the originally white-written role, prompting script adjustments that add dramatic tension in the 1980s Arkansas setting, including an interracial marriage to Amelia. Scattered dialogues on race relations surface in episodes but stay secondary to the mystery and character arcs.

Creator statements emphasize telling an individual's story over explicit racial messaging, with no source-material swap or premise overhaul. Reception notes these elements as vague or perfunctory rather than central, keeping the overall narrative grounded in the crime drama without activist framing or thematic dominance.
