Parasite is director Bong Joon-ho at his very best. It's a departure from the sci-fi bent of his recent movies, though it's no less concerned with the state of society today. Set in Seoul, South Korea, the families and class issues at play reflect our global era, in which the disparity between the haves and have-nots seems to be widening. Parasite follows the Kim family, who secretly scam their way into the lives of the wealthy Park family. Slowly and methodically, the Kims begin to drive out the other domestic workers at the Park residence, each time referring another family member (who they pretend not to know) for the vacant position. And so the poorer family starts to settle comfortably into the grift—until a sudden realization turns their lives upside down. The resulting film offers an at turns hilarious and deeply unsettling look at class and survival, its essence echoed in the environments the characters inhabit.
