By Sandy Cohen, The Associated Press It’s not the acting or the action that makes “Jack Reacher: Never Go Back” inferior to the original 2012 hit. It’s the story. The first film, “Jack Reacher,” established the title character as a brilliant, brutal loner dedicated to justice. He’s a former military officer turned drifter, unfettered by emotional ties, motivated purely by exacting righteousness. What makes an archetypal character like this fun to watch is an unpredictable story, where the audience and protagonist together uncover the mystery.
