If there’s merit in the idea of pretending each season of The Knick is one 10-hour-long movie, “Not Well at All” more than matches the position staked by the first season’s eighth episode: a headlong plunge into bleakness that abridges and re-contextualizes earlier breakthrough moments—not that things were looking especially up in this season’s previous go-rounds. Three of the show’s main characters—Dr. John Thackery (Clive Owen), Dr. Everett Gallinger (Eric Johnson), and heiress/socialite Cornelia Showalter (Juliet Rylance)—are thrown existential curveballs that render their respective ethics systems powerless. Meanwhile, the Knickerbocker’s administrative head, Herman Barrow (Jeremy Bobb), manages to move apartments and purchase the freedom of his girlfriend, a young sex worker named Junia (Rachel Korine). While it’d be impossible to watch five minutes of The Knick without noticing the show’s (sometimes too-harmonized) juxtapositions of class structure, this episode sees its characters ground up especially in the gears of their own patriarchal systems.
