“Land of the Dead” (2005) is writer/director George Romero’s fourth film in his “Night of the Living Dead” series and is possibly the most underrated installment so far. The film offers a variety of new twists to the series such as the development of basic problem solving skills among zombies and the not-too-subtle symbolism of a walled city ruled by a dictator from the top of a luxury high rise. It continues and heightens the social commentary most apparent in the second film of the series, “Dawn of the Dead” while steering it in surprising directions. While the film is not without it’s share of plot holes, it’s screenplay is satisfying nevertheless, and features good performances from Dennis Hopper, Simon Baker, John Leguizamo, Asia Argento and Eugene Clark (with surprise cameos by Shaun of the Dead’s Simon Pegg and Edgar Wright).
