Are you ready to get down with the sickness? Movie logic dictates that you shouldn't remake a classic, but Zack Snyder's "Dawn of the Dead" defies that logic and comes up a winner. You could argue that George A. Romero's 1978 original was sacred ground for horror buffs, but it was a "low-budget" classic, and Snyder's action-packed upgrade benefits from the same manic pacing that energized Romero's continuing zombie saga. Romero's indictment of mega-mall commercialism is lost (it's arguably outmoded anyway), so Snyder and screenwriter James Gunn compensate with the same setting--in this case, a Milwaukee shopping mall under siege by cannibalistic zombies in the wake of a devastating viral outbreak--a well-chosen cast (led by Sarah Polley, Ving Rhames, Jake Weber, and Mekhi Phifer), some outrageously morbid humor, and a no-frills plot that keeps tension high and blood splattering by the bucketful. Horror buffs will catch plenty of tributes to Romero's film (including cameos by three of its cast members, including gore-makeup wizard Tom Savini), and shocking images are abundant enough to qualify this "Dawn" as an excellent zombie-flick double-feature with "28 Days Later", its de facto British counterpart.
