If Boris changed our entire legal system to align it with his libido and fathering skills, presenting himself as the epitome of fatherhood and the women he cheats on as lucky to have been impregnated by him - then I would want to hear it from a different perspective, yes. I'd want someone to bring up that he criticised single mothers whilst shagging around and creating single parent families in his wake - that's the equivalence to Henry and Six. It's adding an angle, not a rewrite.
I think SIX is brilliant. It doesn't touch on trans issues, of course not - it's historical, but that doesn't mean that it doesn't touch on a lot of important, feminist points that persist today - from preference for sons, to girls being seduced and married off as teenagers, to the way stories are often told as women essentially fighting for a desirable man and then driving him to violence. The people here commenting on it without actually seeing it or listening to it are doing the same as people commenting on JKR's essay without reading it.
For example, Anne of Cleaves - history says she tricked Henry into marriage by having a portrait more attractive than she really was... poor, manipulative, ugly Anne. For her section, SIX has a song about beauty standards actually killing you and then makes you think/realise that she was by far the luckiest wife and had a nice life without the limitations of the royal husband that dominated and ruined the lives of the other five. He looks a bit of a pillock for trying to take her as a wife after only seeing a painting. Almost everyone comes out thinking that if you had to choose to be one of the wives, you would be her - so instead of rejection, you see her getting off lightly.
I'm not a historian, I didn't even study history at school but I'll honestly say that Wolf Hall and SIX have both changed the way I think of Henry 8th - added context and dimensions - which is what art is for. TBH it wasn't that I agreed with his portrayal, I just hadn't really ever given him much thought, but I know that now I will have talking points for when my DD is learning to recite his wives by the way they died.
The writers have been ridiculous though, I'm not defending them.
