These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Classic Doctor Who Twitter Blog
Ensemble Darkhorse: Despite only being in two serials, Omega has his own tag on the Blog for a reason.
Ho Yay: Again, if it happens, it will be pointed out. Litefoot and Jago from "The Talons of Weng-Chiang" are an interesting example of characters that Hannah found slash-able but would not ship herself.
Peri, during "The Twin Dilemma". Hannah repeatedly appreciates her frequent What The Hell Hero's after finding her annoying and mostly useless in "The Caves of Androzani".
After the disaster that was "The Twin Dilemma". it took the combined forces of "Vengeance on Varos" and "The Mark of the Rani" for Six to be properly accepted by her.
Adric/Nyssa (Speculated in "Black Orchid," but didn't go full on until she listened to The Boy That Time Forgot.)
Three/Jo ("The Green Death" commentary notes that they would make a cute couple "if it wasn't for the age difference.")
Master/Rani ("The Mark of the Rani". That is all.)
What Do You Mean, It's for Kids?: The religious genocide themes of "The Massacre of St. Bartholomew's Eve" and pretty much everything about Sharaz Jek in "The Caves of Androzani" were noted as...unexpected, to say the least.
