“Hounds Of War” (** out of four) was a predictable action potboiler about a a mercenary (Frank Grillo) who is the only one left alive from a group of renegades and has to enact revenge at a group of friends and family (Robert Patrick, Rhona Mitra, Mark Strange, and others) as he fights back to stay alive. Action, intrigue, and combat by-the-numbers in this routine programmer. Grillo adds some style as always but can play this role in his sleep by now and for that matter so can Patrick.
