From Netflix who sent me the DVD:

Jack Reacher (Tom Cruise) returns with his particular brand of justice in the highly anticipated sequel Jack Reacher: Never Go Back. When Army Major Susan Turner (Cobie Smulders), who heads Reacher’s old investigative unit, is arrested for treason, Reacher will stop at nothing to prove her innocence and to uncover the truth behind a major government conspiracy involving soldiers who are being killed.

So what if you have seen one then you have seen all the Jack Reacher films (of all the action films, for that matter)!  Once the action starts I am attracted like a fly to fly-paper. Never mind that Tom Cruise looks much older. At least give him credit: not bad for someone who is now 55 years old. Never mind that his street fighting skills are improbably staged, they are still fun to watch. Never mind that he and his fellow fighters for truth and justice get some unlikely breaks from time to time just to let their side win. Never mind that the last 10 minutes or so are unbearably maudlin. Never mind that our hero can just barely speak an emotive line of script.

Who cares! What you see is what you get and it just plain fun!
