John Wick: Chapter 4 ended the series perfectly, meaning John Wick 5 is a terrible idea that would undermine the flawless ending. The John Wick series started in 2014 with a low-budget 100-minute action movie, and since then, it has grown into this expansive world with detailed lore, and the movies are full of some of the most impressive action sequences ever shot. However, the heart of the series is John Wick (Keanu Reeves) himself, and his seemingly neverending quest for revenge and to escape the assassin's life has always been engaging, but that quest did come to an end in John Wick: Chapter 4.
