A selective critical checklist of notable Monday TV:

Private Lives of the Windsors (8/7c, Smithsonian Channel): The public's fascination with Princess Margaret, Queen Elizabeth's younger sister, has spiked again, 18 years after her death at 71, in no small part due to the popularity of Netflix's The Crown (which will return for its fourth season in November).
