HBO will ring in the Halloween season with a horror story more existential than predatory: Mrs. Fletcher, a “dual coming-of-age story” based on the book by The Leftovers’ Tom Perrotta, follows a single mom who finds herself lost after her son, Brendan (Jackson White), heads off to college. As the high school jock tries to navigate his hyper-woke collegiate campus, Kathryn Hahn’s eponymous Eve Fletcher begins pushing her own boundaries—sexual ones, to be specific, with both women and men.
