Get Millie Black appears to foreground identity themes through its lead, a Black, queer, female detective, often letting these traits define her more than her capabilities or craft. The show frequently signals social messaging, sometimes at the expense of organic character development and classic detective intrigue, which may frustrate viewers craving tighter plotting or a less pointed focus on identity politics.

Traditional cultural and familial structures, as well as masculinity, often play a secondary role or are subtly critiqued within the show’s narrative. The series reinterprets Caribbean and British societal norms through an explicitly modern lens, sometimes casting older traditions as sources of conflict or inconsistency with contemporary values.

Alternative worldviews are rarely given nuance; more traditional perspectives tend to serve as obstacles or are framed as outdated. The show’s ensemble generally aligns with progressive attitudes, and dissenting voices are relegated to antagonistic or problematic roles, lacking genuine debate or internal plurality.
