I know this episode polarises a lot of people, and I can absolutely see why - the male-presenting line is goofy as anything. But that's the extent of my complaints for this episode. I adored it! And all of the 60th, too. 10 and Donna were my introduction to the show and always connected with me really deeply, so seeing them both back together on screen is just. Argh!!
14 is such a cool concept - an old doctor's face coming back and immediately running into someone they travel with is such a great idea that I can't believe it took 60 years to be put into practice (ik it was considered during the end of 5's era with Troughton coming back at least). I've seen people saying that he's basically 10 personality wise, but I definitely disagree. He's obviously a lot more world-weary. There's less of a bravado to him, replaced with a much more emotional openness that 10 never had. Tennant slips back into the role just like a pair of old shoes and I loved every second - the scene in the factory where he's talking to Shirley is a highlight.
Donna!!!! I can't exaggerate how much it means to me, a trans person, seeing her A. have a trans kid and B. be ready to throw hands for said trans kid, it feeds my inner child so much. I would have liked to see a bit more of Rose herself, but the episode is packed enough as is I suppose. Also, I know the line where she's deadnamed isn't... great, and that Russell really didn't need to add time lord-y metacrisis meaning behind it, but I like that its there. Trans people do get discriminated against irl and I think it's important that media uncritically condemns it, which the scene does by making the kids the obvious bad guys.
The Meep is brilliant, both visually and as a character. I vividly remember getting so hyped about how well done it was when they posted the clip of it and Rose in the shed. Absolutely brilliant villain that's a joy to watch cackle away like a cartoon villain.
I don't dislike the Binary, Binary, Non-Binary thing. It's phrased weirdly but it's not the uber-cringe awful teeth gritter I've seen some people say it is.
Overall I loved this episode. Yes there are flaws, but for me personally the positives outshine the negatives, which is the case for me with all the 60th Specials.
