This is the best of the series so far, mainly due to the more varied ways in which Keanu Reeves dispatches his enemies. Halle Berry is good at it too. Plot is largely irrelevant. Enjoy.
• Spare Cycles: Film review: John Wick (Chapters 1 and 2) – Blu-ray version
• Wikipedia: John Wick: Chapter 3 – Parabellum
These films basically involve Keanu Reeves beating up and shooting (mainly shooting) everyone in sight. Put your brain in neutral for a couple of hours and enjoy.
A bit more variation in how he dispatches people would be good though.
I think the films are a bit overrated but Chapter 2 is better than the first and Chapter 3 is coming out on disc / digital later this year. That’s supposed to be the best of the bunch.
