From a director known for his unrestrained writing and penchant for controversy comes an inconsequential zombie flick that a David Cronenberg fan may want to believe is a little more clever than it appears. It’s not, though. That was Shivers, which came out before this. Rabid lacks both Cronenberg’s intelligence (the science of the horror isn’t even attempted an explanation) and his humanity (Marilyn Chambers’s personality is extremely inconsistent and unreadable, and Frank Moore doesn’t get one at all). Completely without any risk.
