The longline is probably something like “famous horror writer finds inspiration for her new book when, with her husband, she takes in newlyweds”. For me it’s in love with the idea of the writer as tortured masochist. Elisabeth Moss is unflinching as the grisly wordsmith. Michael Stuhlbarg matches her as the domineering husband. It’s an internal film, making physical the interior psychology inherent in a book. Think a swim in the shallow waters of Darren Aronofsky’s 2017 film Mother!
