With a new haircut and storyline, Shailene Woodley as “Divergent” heroine Tris Prior is hell-bent on revenge, battling the ghosts of her past in “Insurgent,” the second film in the young adult sci-fi action film franchise. “Insurgent,” out in U.S. theaters on Friday, picks up where the first film in the dystopian series ended, with the genocide of Tris’ parents and the people in her faction after she joins another community. The “Divergent” series follows a post-apocalyptic world that has been divided into five factions, each defined by character traits: wisdom, honesty, selflessness, kindness and bravery.
