Subverting the characters and world building is such a popular thing with scriptwriters at the moment. From DW to Trek to Witcher, writers and showrunners really want to subvert things or break down popular legacy characters in order to make their own creations/interpretations shine.
I love Trek because it is aspirational and has faith in humanity's potential. In its heyday, 1966 - 2005, it was stories about competent, well-trained Starfleet officers with developed ethics exploring the galaxy while navigating danger, contact with alien civilisations, interpersonal friendships and the chain of command. Nowadays NuTrek is just characters snarking at each other on dimly lit sets, rushing around for no particular reason, crying and hugging, and no-one pays attention to the chain of command until Burnham (inexplicably) becomes captain of the Discovery despite constantly ignoring orders from superior officers 🤷♀️ Strange New Worlds is a fractional improvement but not by much because the characters all behave as if they were written by Joss Whedon rather than Trek writers.
And I don't think Headland had to subvert the Jedi to write an interesting story about the Sith - I would have found a good story told from the Sith POV really fascinating (Manny Jacinto shows hints of what it could have been like in his performance in The Acolyte) but I don't think she had the skill to tell that story.
Doctor Who has suffered the same fate - they've taken the iconic character of the Doctor and reduced his gravitas, as well as his importance in his own show, in order to give more attention to female companions (that are written like the showrunner's idea of a dream girl) and an emphasis on romantic entanglements. Also, I'm not interested in the home lives and family circumstances of his companions: I know very little about the background of Jamie, Tegan, Mike Yates, Jo Grant, Sarah Jane, Lyssa, Turlough or Adric and I still found them to be fascinating characters. We lost intelligent plots dealing with science and ethics to plots with explosions and fights and London being invaded and general timey-wimey nonsense. Plus, stop expanding what the sonic screwdriver can do, it's turning into a Deus Ex Machina Multitool.
I can't understand why writers and producers want to make things they don't understand or like enough to treat faithfully and well. Look at what Denis Villeneuve did with Dune - he stuck to the lore as much as possible and made as few changes as he needed to to translate a complex book full of interior character monologues into a film. Why can't we have more of that sort of thing?
