Luther/YMMV
- Alternate Character Interpretation: The grey hero of the series, DCI Luther. True Cowboy Cop who is on the edge and will stop at nothing to make sure that the worst of the worst are stopped? Or is he a burnt out cop unable to feel for the victims driven to win by his sense of self worth? A man so apathetic to all the horror that the only person he can relate to is a cold-hearted killer.
- Alice Morgan, a cynical genius whose outlook on the Universe -- how everything and anything can be rendered into pointless nothing -- led her to murder her parents after years of hidden resentment. Or a brilliant young woman shaped by being seen yet unseen who relishes her time with Luther as he knows her real self. And will do anything to help the closest thing she has to a friend. Including, as of episode four, Murder Henry Madsen.
- Complete Monster: Let's face it, Luther may be a short tempered and volatile cop who boarders on Knight Templar, but those he is up against are so very much worse. Cop killers, a needy genius who commits patricide, a satanist who bleeds his victims dry and a multiple murderer who kills women as a form of aphrodisiac.
- Crowning Music of Awesome: The title theme "Paradise Circus" by Massive Attack, and happens to be a pretty good summation of Luther's character.
- Fridge Logic: Why would Mark believe Luther's claim that he's innocent of Zoe's death, especially when he's working in cahoots with the woman who was behind him being beaten up?
- Nightmare Fuel: The pin in the ear scene.
- In episode three a satanist has a thing for writing in human blood. Thing is, he tends to write whole novels at a time.
- Magnificent Bastard: One could make a strong case for both Alice and Luther.
