Warning: Major spoilers for David Fincher's The Killer below!The Killer's extended opening sequence pays homage to a classic Charles Bronson thriller from 1972. On the surface, David Fincher's latest may have looked like a typical hitman thriller, but his Netflix movie is really a dark comedy. Michael Fassbender's titular assassin may think of himself as a sleek killing machine, but he makes constant mistakes and miscalculations throughout the story that make his situation even worse. Some critics have read The Killer as a parody of Fincher's own reputation as a perfectionist, with Fassbender's character having to live with the consequences of only having one chance to get things right.
