I've never seen Doctor Who. I understand it's a camp cult hit from the 70s and 80s that got lucky with a reboot.
But the show's core purpose now seems to be a vehicle for identity politicking amongst the UK left. The producers seem far more interested in casting as an end in itself - basically fetishising it - rather than in what the cast are actually portraying. That's really creepy when you think about it. It feels like you're in for a thinly veiled ad for DEI, as opposed to a compelling SF narrative. Tail wagging the dog.
You say you've never even seen Doctor Who before so by your own admission your opinion is uninformed and therefore offers nothing of substance. This is a community for discussing movies and television. Not your personal soapbox for airing your uninformed culture war grievances. Take that somewhere else.
Whether I've watched it isn't relevant. This fashion of creative autonomy being sacrificed to meet casting diversity KPIs is also being noted by the article's commenters. It's one factor behind the familiar criticism of much modern TV - that it looks and feels the same, genre to genre, studio to studio.
