Oh, I’m not denying Diana was ill treated. It’s just not interesting to watch scene after scene of an irredeemable asshole and the beautiful, put-upon young woman (good lord, Emma Corrin is beautiful) who seems blameless. I mean, hell, maybe it’s 100 percent true, but it was kind of a drag to watch.
Piling on Charles being psychotically jealous of her popularity really detracted from the story, to be honest; that could have been entirely left out. In one scene, Anne flat out tells her mother that Charles and Diana are hopelessly incompatible; what we should have seen was more of the incompatibility (rather than Anne TELLING us, though that scene should remain in; if you have that scene later it’s useful to demonstrate Anne’s perceptiveness and to explain how Her Majesty hears it.) That is a more interested aspect of the story than just “Charles throws a screaming tantrum when Diana gets attention,” and can be played with more subtlety.
I’m not sure that’s an objectively defensible position; I think that on average, they’re as nice as anyone would be under the circumstances. Andrew is a sex predator, I guess, but you can’t pin that on anyone but him.
I am not the first person to point this out, but while people endlessly lionize Diana for the charity work she did, Princess Anne has been doing twice as much her whole life and no one seems to notice because she’s not as pretty.
