(Reposting this from /o/Books, since many of the recs I received were actually TV shows)
Recently, I started reading Patrick O'Brian's Aubrey-Maturin series of classical nautical adventure novels. A key component of these novels (and what attracted me to them in the first place) is the deep and abiding friendship between the two main characters, Jack Aubrey, a Royal Navy officer, and Stephen Maturin, a physician and natural philosopher. The men are as unlike as can be in background/personality, yet bond over their shared love of music, and throughout the series go on many adventures together and make many sacrifices for each other. Their friendship extends through most of their lives.
It struck me that I had never heard of a story featuring such a long-lasting, devoted platonic friendship between a man and a woman. We have Aubrey and Maturin, Holmes and Watson, Kirk and Spock, Frodo and Samwise... but when it comes to male/female couples, they inevitably amble down the tired, well-trodden path of sex/romance, marriage, and babies. Usually, this also involves butchering the female character's personality so she is overjoyed to have those babies, despite showing zero inclination before meeting our intrepid male hero.
So, here's my question. Can you recommend any TV shows or related media that depict a deep platonic relationship between a man and a woman? Some suggestions from the other thread: Janeway and Chakotay (Star Trek: Voyager), Leslie and Ron (Parks and Recreation), Holmes and Watson (Elementary), and John Steed and Emma Peel (The Avengers).
