The planet Mars, which fared poorly with critics and audiences alike in its recent film appearances (Mars Attacks! , Mission to Mars, Red Planet) is not doing much better with John Carpenter's Ghosts of Mars. "Occasionally veering into that so-bad-it's-good category," Liam Lacey comments in the Toronto Globe and Mail, "mostly Ghosts of Mars is just so bad." Many critics simply found the movie boring. "It's like a zombie picture directed by one of the undead," Elvis Mitchell writes in the New York Times. "We knew Mars was a dry planet, but this dry?" Jay Carr remarks in the Boston Globe. Steven Rea in the Philadelphia Inquirer disagrees -- sort of. "While this cheesy, heavy-metal melange of horror, space hooey and cowboy shoot-'em-ups isn't exactly dull," he concludes, "it isn't anything to write home about either. In fact, it's hardly worth writing a review."
