John Wick: Chapter 4 was the franchise's biggest movie yet, and while it saw many of its most recognizable characters return, Halle Berry's Sofia was one noticeable absence. After the high expectations set by the first three films, John Wick 4 continued its box office win streak and delivered another quality action film that is arguably the best in the series. Like its previous films, it made four times its budget, becoming the highest-grossing movie in the franchise. Not only did the action level up once again, but John Wick 4 somehow managed to raise the stakes once more and ensure the investment in a fourth film paid off.
