Wading in late
Given the Missy/Master gender discussions in "The Doctor Falls", this should really have not surprised anyone. The interplay of the two incarnations of the master was really the most delicious acting I have ever seen in Dr Who.
I got into Dr Who a few years ago, at the tender age of about 52 (my Missy found some disks for our son to watch, and we were all hooked- in Finland, the Doctor was not on TV when I was a child). Probably a heretical opinion here, but I find the "new" episodes better than the classic ones, which frankly are quite dated, and not just because of their cardboard sets and primitive special effects. The acting is usually better in the new ones, which makes the totally implausible stories fly.
Eagerly looking forward to seeing where the thirteenth Doctor takes us.
