“Sniper: Ghost Shooter” (** out of four) was an umpteenth entry in this mediocre and wearily repetitive series starring Billy Zane and Chad Michael Collins as sharpshooters entrusted to protecting an American gasline. When a ghost shooter mysteriously appears and starts killing both foreign and American subjects, everyone starts to wonder. In keeping with the motif, I’m starting to wonder why they have made so many sequels to a 1993 action movie that was terrible to begin with. First-half is sluggish; second half has some good firepower. Seriously though, folks, the thrill is gone. For a movie with more riveting action and emotional complexity than all 6 of the “Sniper” films combined, watch “American Sniper” instead.
