2014’s “John Wick” was a relatively simple affair. It was a revenge picture with clear antagonists and a straightforward mission of payback, using extreme violence and brutal style to reinvent the action movie in a genuinely thrilling manner, using just about 95 minutes to get the job done. Lean and mean. “John Wick: Chapter 4” is anything but lean, asking audiences to be patient with its gargantuan 165-minute-long run time, with the character set on a globetrotting mission of fury, still managing to survive all sorts of physical attacks. The new sequel is definitely mean, with returning director Chad Stahelski absolutely determined to top himself with this new wave of furious stunt work and extended choreography, once again putting star Keanu Reeves through the paces as John returns to power in this exhausting endeavor, which still retains many cinematic highs, but good heavens, does it ever need a few more passes in the editing room.
