George A. Romero's gutsy follow-up to Night Of The Living Dead and Dawn Of The Dead sees a group of edgy scientists and military men cooped up in a silo surrounded by thousands of zombies.
While a mad doctor tries to train zombies to be useful citizens, a madder army officer is threatening to have people summarily executed if they sit in the wrong chair, and the heroine is wondering whether it's worth striving for the continuation of society.
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, plus one of the all-time great dismemberment sequences as a villain shouts "choke on 'em" to the monsters eating his innards.
