Cashiers du Cinemart. Film Threat's Dave Williams: "a thin, primitive hobby publication with an obvious ax to grind; making it far less interesting than you think it is, and compelling me to conclude it's impossible for you to ever get your shit together...killing one more tree for your pointless, directionless, self-aggrandizing 'zine with nothing to offer is a sad, selfish waste."
