Here, a pessimistic Romero dares to tackle the very essence of man’s inhumanity to man. And in the end, Day of the Dead is every bit as compelling and unsettling as its more lauded predecessors.

It's an intelligent, well-written, excellently played movie, with top flight gore/horror effects, perverse humour and a provocatively bleak vision. Also, it has the world's first true zombie hero in Bub, who listens to Beethoven and eats people.

Tense rather than terrifying, and with a strong black comic undercurrent, it rests on the mordant observation that zombies or no zombies, chances are the living will tear each other apart. A fitting conclusion to a remarkably astute series, a landmark in the horror genre.

Day of the Dead has a less startling setting, since most of it takes place underground. But it still affords Mr. Romero the opportunity for intermittent philosophy and satire, without compromising his reputation as the grisliest guy around.

Day Of The Dead is more like Romero's scorching 1973 satire The Crazies, in which anarchy reigns and the very concept of heroes dissolves. The action at the end is lurid, made giddily disgusting by Tom Savini's amazing gore effects, and made gripping by Romero's gift for the cold logic of systemic breakdown. Still, some audiences may give up early, fed up with the shrill claustrophobia.
