Some people were appalled at the learning curve of Big Daddy and his throng of followers but I thought it was a fresh and revolutionary upheaval of the status quo in these movies.
Romero always infuses his spine-tinglers with a blast of ripe social commentary and 'Land of the Dead' explores the post-apocalyptic class system, the distraction tactics of wartime (the zombies are inordinately fond of fireworks) and the underestimation of the enemy (zombies are pawns for amusement). George Romero had been on a self-imposed hiatus before 'Land of the Dead' but he strikes back with a vengeance in this brisk fourth installment.
