The Diplomat bears the same relationship to 21st-century ambassadorial geopolitics as Bridgerton does to the salons and social mores of early 19th-century England. The latter is Jane Austen as reimagined by a wannabe Jilly Cooper with a first-class degree in historical revisionism; the former is a bit like what The West Wing might have been if it had been written by Dan Brown and those behind the classic, early 1980s husband-and-wife mystery drama Hart to Hart.
