2 hour and 49 minutes were too long, or I was hungry so I couldn't wait for some action scenes to be over. For example, when John Wick fell down the stairs, the first two flights were good, but the last two flights, c'mon, that was ridiculous.
Speaking of ridiculousness, why didn't John Wick die falling off three floors, but his opponent died?
Do not watch this movie with logic and plot. This movie has become a commercial for men's formal wear and beautiful cities. When John Wick was in Osaka, they basically piled on all the tropes. Cherry blossom, samurai warriors, sumo wrestlers, and honorable yakuza leader. Has Hiroyuki Sanada become the de facto Japanese gravitas actor? It was Ken Watanabe before. Now Hiroyuki Sanada is in Bullet Train and John Wick.
The most unrealistic thing about this movie was the subway train was absolutely empty when John Wick stepped on. Then Hiroyuki Sanada's daughter happened to get on the same train and the same car, one out of at least 10 cars for any given subway.
Then John Wick went to Paris. Oh, the beautiful Paris. I'm sure there were tons of tropes in the movie for Paris, but I wouldn't know any.
Math Teacher didn't like the people lost respect and fear for John Wick. In Chapter 1, John Wick was "the one you sent to kill the Baba Yaga." In Chapter 3, the final opponent was honored to fight with John Wick. In Chapter 4, the villains just grabbed guns and shot him up. No more respect.
Therefore, I applaud the filmmakers to have the guts to end John Wick and to end this franchise. Nowadays people want to squeeze more money out of nothing, but the filmmakers here gave John Wick a fitting farewell.
