The film balances its horror and sci-fi bones with satirical teeth. Corporations hawk synthetic blood like consumer electronics; advertising jingles chirp through blood banks; politicians and CEOs posture about “sustainability” while donation queues lengthen. The city itself is a character — chrome and glass, always darker than the next sunless alley. Yet director Michael and Peter Spierig (the Spierig brothers) keep the human scraps visible: addicts clinging to a last tether of humanity, doctors bargaining with conscience, and the way desperation breeds both cruelty and surprising tenderness.
