There's one I saw -
Doctor's Diaries. This was WAY back in the day. Things have changed but it kind was an interesting take where they followed people going into medical school and how things turned out 20 years later.
A non-documentary TV series I enjoyed was A Young Doctor's Notebook. It's 2 seasons but really is pretty up there in terms of good medical TV.
In honor of this thread i rewatched doctors’ diaries. Initial watch was right before MS1 this time just as I begin by 3rd year of practice 13 years later. Wow what a good documentary that was (for sure then even more so now all these years later)
