London Kills features a modern, diverse cast, which at times feels guided more by box-ticking than strict narrative needs. However, most characters carry personal flaws and skills integral to the plot, so the story isn’t outright derailed by ideology. Forced representation pops up but isn't overwhelmingly disruptive to the core detective storyline.

The series gently nudges tradition aside, downplaying family backstories and rarely highlighting traditional values. There’s little focus on religion or masculinity, which could be seen as a typical modern procedural move. Still, it doesn't go out of its way to attack or mock those foundations, just quietly sidesteps them.

Most characters embody current progressive social perspectives, dissenting or traditional views are largely absent and, on rare occasions, are presented in unflattering lights. Pluralism or robust internal debates are rare, making the worldview feel a bit one-note, though not aggressively so compared to more overtly activist shows.
