This season has been imo one of the best period (Heaven Sent is easily top 3 best Doctor Who episodes for me alongside Blink and Midnight and just edging out The Eleventh Hour).
My take is that any great actor/actress could be awesome...But I also know that there's other factors involved beyond just their race/ethnicity/gender. The person has to be British (or what do you call a person from the United Kingdom? A UK'er? ), has to want the position, have the availability and desire to commit to the job, and be good...
Jodie Whittaker is an AMAZING actress...I would've been happy with Colin Salmon (my dream Doctors are Idris Elba or Patrick Stewart or Hellen Mirren LOL) or any number of male, white, female, East-Asian thespians. I'm just glad they chose someone who is a stellar performer and has experience with the showrunner.
I'm Team Remender, Waid, Hickman and Gillen
My X-Men Draft Picks:
Prof. X, Legion, Polaris, Quicksilver, Meggan, Deadpool, Pixie, and Danger
