“Kill Plan” (**1/2 out of four) was an overly derivative but diverting action-spy potboiler about a seasoned F.B.I. agent (Jason Toler) who is thrown into a multilayered deception involving a covert government plot to unleash a deadly drug on humanity and thus lead to a pending apocalypse. Too many twists and turns and secondary characters which unnecessarily thicken film’s murk but overall slick and entertaining with enough gunplay and martial arts to make it worthwhile for genre fans. Toler is rock-solid in the lead and helps make up for film’s other weaknesses.
