“Dickinson,” which premiered in 2019, is now the breakout hit from Apple’s slate of original television shows. The series might have climbed from the brain of a woke English grad student on an acid trip. In the pilot, Death, played by the rapper Wiz Khalifa, whisks Emily away on a carriage ride, during which he promises her immortality and foretells the carnage of the Civil War. (Spoken by a Black actor, the warning carries a retributive chill.) Another episode, drawing on actual Dickinson scholarship, explores Emily’s erotic awakening as a function of her relationship with Sue, the fiancée of her brother, Austin. The episode is called “I Have Never Seen ‘Volcanoes’”; the series gives pride of place to real Dickinson verses, which materialize, onscreen, in a golden scrawl.
