Why is Parasite brilliant? Let me count the ways. The mix of comedy, drama and horror is seamless. Each choice director Boon Joon-Ho surprises us without any contrivance. The film works on so many levels. The class struggle between the two families gives Boon a chance to tear the scabs off the have and have nots. The imagery roars. An apocalyptic flood of sewage gives way to a cleansing baptism. Boon takes us on this wild abstract trip without letting his directorial flourishes derail the plot. Korean politics gets strung out. The technical aspects of the film along with acting and writing never falter. Parasite earns its status as a masterpiece.
