David Fincher’s The Killer plays like a cold meditation on modern existence disguised as a hitman thriller. Fassbender’s assassin is a man obsessed with routine, discipline, and control, repeating mantras to quiet the chaos of the world. Yet the film slowly reveals the futility of this philosophy: no matter how carefully he plans, accidents, emotions, and human unpredictability seep in. What emerges is less about crime or revenge than about the absurdity of trying to impose order on an indifferent universe. Detached, meticulous, and quietly bleak.
