When I saw the first post earlier this morning I thought it was hypothetical. Then I saw an article later in the day from Tom Baker saying it was about time that there was / is a female Dr Who. I thought Wow, Pearl is on the ball !
I do not know anything about Jodie Whittaker. Is Steven Moffat still writing for Dr Who? If so I am sure he made a good choice. I really like his work in the series
Coupling as well as
Jekyll. From what little I have seen of the newer Dr Who's here in the States his selection of Michelle Gomez as the female Master / Mistress was very well done. She is a great actress and I really like her in the
Green Wing series
. Also, as mentioned I think Olivia Colman would have been great as well - fan of hers too.
I must admit that at the time I was a bit unsure at first of a female Starbuck in the remake of
Battlestar Galactica. The idea of it put me off watching the show till several years later. The original series was near and dear to me watching it as a kid on the tele back in the day. Yes, I thought it sacrilege to recast a major role like that. Wow, was I wrong when I eventually got around to seeing the remake. I really liked what they did with the show. Sadly, as the series wound on through the years the writing did not seem as great as it first was. Unfortunately this affliction seems to strike many shows nowadays. I'll still re-watch the first few years of the series gladly.
As mentioned the Dr is not human and most likely took a human male form to more easily and covertly integrate with human society for his travels back in the day when the show came out. Can you imagine the Doctress chasing after Dialeks and other meanies in a big, poufy
Pride & Prejudice Jane Austin type dress through alien landscapes

?! Just teasing. I do realize that Dr. Who is an iconic, classic British show and has much meaning to the many who enjoyed it over the decades. I've enjoyed many a Dr Who shows through his multiple regenerations over the years.
I just remembered watching a Dr Who special episode with Rowan Atkinson as the Dr. some time ago. Julia Sawalha was his cohort. Then near the end of the special the Dr regenerated into Joanna Lumley! Hmm, must have been very foretelling of the future Dr Who plans.
Cheers,
