Viewers were promised more of the world building regarding the criminal world (and hotels) through which John moves. The promise was full-filled, although scantily. This time we learn that this world is international, spending one third of the film in Rome (and under it). Again it’s beautiful surroundings, beautiful people and some worrying rules these people live by.
But mostly it’s violence. With weapons, without. On the roof, under ground (and in the underground), anywhere. But don’t worry about the dog this time, Wick does it utterly, completely by himself.
