Unrelentingly kinetic and action-packed crescendo of a polished B-movie that is interspersed with moments of lull as to prevent an overdose. Performances are competent and compelling, and dialogue is neither formualic nor hollow, effective direction grounds the characterizations and scenes, realistically to easily connect to the audience. Zombies are somewhat lacking but this is a great war movie, unique, fun and entertaining as hell. Had a good time.
