“Boneyard” (** out of four) was a meager suspense thriller about various law enforcement agents (Mel Gibson, 50 Cent, Nora Zehetner, Brian Van Holt, and others) who all collide in attempting to capture a brutal serial killer who collects and disperses bones of different female victims. Good cast is unable to enliven all-too-familiar and unpleasant material; the underrated Van Holt fares best as the lead detective on the case but Gibson and 50 are both wasted. Based on a true story but seems even more based on previous serial-killer stories “Seven” and “The Bone Collector.”
