The appeal of Jack Reacher seems obvious but remains elusive onscreen. The creation of Lee Child, Reacher is one of those enigmatic, borderline mystical types who surface out of the haze to handle villainy with boundless intelligence, weapons mastery and annihilating violence. In the first movie, “Jack Reacher” ( 2012) , the menace begins with a multiple shooting that leads to a conspiracy, false charges against Reacher, a damsel in distress and swarms of villains. It’s ugly, pessimistic world overflowing with so much wrong that of course it has spawned a sequel with the same dreary beats.
