“Baby Reindeer” and “Under the Bridge” Are Strange

When Donny Dunn (Richard Gadd), the protagonist of the autobiographical Netflix sensation “Baby Reindeer,” recalls the act of kindness toward a stranger that would come to derail his life, his initial explanation is deceptively simple: “I felt sorry for her.” Donny is a fledgling comedian in his late twenties, tending bar at a London pub to make ends meet. Martha (Jessica Gunning) is a heavyset, middle-aged frump who claims to be a high-powered lawyer but simultaneously insists that a cup of tea is beyond her means.
