Kim K'atek and his near do well family literally living in the lower depths catches a break when their son obtains employment as a tutor for a wealthy family. Craftily the family conspires to inveigle its way into the household of the Parks by getting the chauffeur and longtime housekeeper fired and setting themselves up inside the lavish domicile with a Garden of Eden for a front yard. Things quickly take a turn however when the housekeeper returns for something she left behind.

Working with basically two class defining sets Parasite is a well filmed an interesting watch with the plot slowly unfolding in a darkly comic fashion before going into self induced chaotic free fall from the plausible to the absurd with a hurried climax and unsatisfying epilogue. Director Joon Ho-Bong and cinematographer Kyong pyo Hong do an excellent job of contrasting settings, situations, jabs about class and characters early, equally dividing the roles of his adult characters all benign and petty in their own way. It adds to the fascination of where this slightly off balance plot is going when the wheels come off. With no end game to the plot Ho-Bong decides to end it in conflagration and an insipid post climax that demands it defy logic.
