To be a good killer you need to follow strict rules with a margin of error as close to zero as possible, expected but not admissible.
In an initial twenty-minute voice-over monologue and with an almost line-free performance for two hours of film, Fassbender, directed by Fincher, delves into the dark abyss of a character made of shadows, silences and a maniacal control of emotions to present and return an absence of life, in perfect synchrony and coherence with one who takes life away.
The prologue is of such remarkable cinematic power that everything else goes without saying and flows anyway because it exploits the propulsive force of the beginning which is enough and goes on.
Michael Fassbender is an infallible killer, from his hotel window he waits for his target, a routine now. Everything is planned, as usual.
