John Wick: Chapter 4 is the culmination of an almost nine-hour story about the very sad and very violent life of its title character, a former hitman who just wanted to live a humble life with his puppy dammit, but cannot seem to escape his past as a killer for hire. And most of those nine hours have involved action scenes of every imaginable kind: Hand-to-hand combat, shootouts, sword battles, knife fights, along with chases on motorcycles, cars, and even horseback. How do you bring all of that to a close and top what you’ve done before, all at once?
