The movie has more outlandish set pieces, more flashy locales ( from Times Square to the Sahara to the groovy, aquarium-like boardroom of the assassins’ Ritz, the Continental Hotel) , and a cityscape bejeweled by candy-colored lighting. The cast has been beefed up with likable actors — not just the familiar Ian McShane, Lance Reddick, and Laurence Fishburne but Halle Berry, Angelica Huston, and the charismatic Mark Dacascos as a sushi chef–samurai–John Wick fanboy. The plotting is no longer linear: It’s positively labyrinthine, with a mythical universe of godlike assassins and their minions. The movie should by rights be a “Wow! ” But it feels bloated, self-conscious, and pretentious, with long waits between its few dazzling fights. Evidently, it’s hard to build on a premise that’s basically so vacuous and dumb.
