Months after Jordan Peele’s Us explored the haves and have nots dunking it out in a surreal version of contemporary American society, Bong Joon-ho’s Parasite (A-) elevates class warfare to a whole new milieu via a dark comedic story of the extraordinary denizens of a blissed-out South Korea metropolis. The visionary director introduces viewers to a lower-class family of four rising to roles in a posh home tutoring, cooking for and driving the domicile’s privileged occupants. Is this jaw-dropping story a searing supernatural thriller or a ghost tale, dramatic chess game or upstairs/downstairs allegory? With shifting mixed-genre shenanigans, it’s all these and more. The film is fierce, frisky and funny as it makes salient points about the underbelly of society with inhabitants clawing for a way out of the funk of a bunker mentality. Favorite characters in this twisty treat are the resourceful sister played by Cho Yeo-jeong and the prideful and practical father portrayed by Song Kang-ho. The mansion at the center of the narrative is a fantastical fixture almost as labyrinthine as the pulpy plot points. Aside from some silly pratfalls and a lugubrious epilogue, expect consistent shock and awe from this inventive cinematic import.
