The John Wick franchise blew up as soon as its first film was released, as people were enamored with the stylized world of a secret society of assassins, with one standing above all as the greatest killer of all time: John Wick (Keanu Reeves). Perhaps the greatest aspect of this quadrilogy is that every time we think that stuntman-turned-director Chad Stahelski has surely mined all the narrative potential of this on-paper basic character, he finds new ways to give us thrilling set pieces and deeper layers of lore for John Wick to interact with, producing four of the best action films released in the 21st century and making interest in a fifth film so high that Reeves had to come out and confirm his character was indeed dead following the end of John Wick: Chapter 4.
