The Crown on Netflix is also very good. Thought I would hated considering;
a) I hate historical fiction and
b) I'm not the biggest fan of the monarchy
However, I am finding it quite enjoyable. The acting is incredible, and they all look very similar to the people that they are playing, which I appreciate. Though of course, I'm not taking anything depicted at face value, it does appear to be, for the most part quite well researched, and rather than focusing on fictional, yet explosive plot details (keep in mind I'm only on the first season, so can't comment on the second where pretty sure they delve into unverified, though probable stories of affairs), like many other shows about the royal family, it is a lot more character driven. I do wonder though whether they are being a bit too kind to some members of the royal family, in particular Queen Elizabeth. Maybe its just my innate distrust of the monarchy talking aha, but I think she's coming off quite well in this show aha.
Overall, I recommend
Though it would probably be better to go into it with some understanding of the basic history of the royal family in the 20th century, as it can sometimes get a bit confusing. You don't need to know that much, but a bit about the abdication of Edward VIII wouldn't go a miss
