Writer-director Jim Mickle has steadily established himself as a horror filmmaker with interests that treat the art of shock value with rare maturity. In his feature-length debut "Mulberry Street," he funneled the mold for a cheesy monster movie into a metaphor for gentrification and urban decay; his follow-up, "Stake Land," imagined a B-movie universe of vampires versus humans with soft-spoken exchanges and lyrical imagery that instantly called to mind Terrence Malick.
