Spoilers below for “My Lady Jane.” One fan said on X, formerly Twitter, “Y’all are so good about hiding plot details bc what do you mean the main guy in My Lady Jane is a HORSE.” Another fan proclaimed that the show feels like “if they wrote Bridgerton while on ketamine.” “I think the main reason I can’t stop thinking about My Lady Jane is because it is a television manifestation of a phrase I have had stuck in my head since 2007, which is, obviously, ‘His “wife”? A horse,’” another viewer shared. “My Lady Jane,” which is based on a book series, is set in the sixteenth century. It follows Lady Jane Grey (Emily Bader).
