“John Wick- Chapter 3: Parabellum” (** out of four) was a flashy but empty third entry in which the title character John Wick (Keanu Reeves) is once again on the run after killing someone from the International Assassins Guild and becomes marked for death by a sinister female underworld crime boss (Asia Kate Dillon). Director Chad Stahelski bathes this in the same extravagant style and ultraviolent action (there are some showstopping action scenes) of the first two but there’s nothing to hang them on, because story is thin and weak and film’s middle lags. As long as the eye-filling action is on screen, film is entertaining but when story and characters take over it slows to a halt. Preposterous ending leaves the door open for yet another sequel.
