Deadline has a very interesting speculative article on all that went down.
One of the comments caught my eye, regarding 15, and it left me with a question that I'll ask after:
It didn’t help that neither Whittaker’s wildly inconsistent weak woman incarnation (who spent one episode complaining about being tired standing up while an OTT gay villain mansplained her origins to her and went from the Doctor’s traditional role of disruptor to champion of the status quo) or Gatwa’s all-out on the gayness but lacking in any other dimension were strong or interesting enough personalities to compensate for the bad writing the way every previous Doctor did.
What other dimension did Ncuti bring? He brought joy, and his electric smile. And when he got mad, like in Dot and Bubble, it was a really nice change. But despite knowing the Doctor so well, I feel like we never really learned much about this Doctor. Part of that is so few episodes and the insistence on RUNNING, part of it is performance - he was either giant smile or streaming tears. Otherwise, the rest was all "honey" and "babes" which always felt like the actor - not the character.
I still haven't seen Jodie's seasons so can't comment on that part of the quote but left the full comment in for context. The article also mentions the streaming rights for the full series are now available - I hope they get combined again. Not having the history easily available is no fun. Especially for a show about history.
