Well, Moffat can say what he wants. He's the current showrunner, but he'll be gone eventually. They can go against Big Finish whenever they want, it just doesn't really come up because they don't cover the same territory very often. I'm sure they'd treat BF like the fanfiction it is if they had the slightest desire to do something that happened to contradict Big Finish.
The closest they've come to contradicting a BF story is
The Fires of Vulcan, and even then they stressed out how they take place at the same time.
BBC wouldn't outright contradict BF. Both BBC Wales and BF work together on scripts, to make sure BF won't do a story that BBC Wales wants to do. And considering Big Finish will now fully do stories with NuWho characters, starting with Torchwood and UNIT and continuing with River Song, you can bet that bond will be stronger than ever.
That's just personal opinion, so I won't really argue too much. I love his real coat, but if you like the non canon coat better, that's fine. I think its stupid and only exists because some people just can't accept reality.
Some people? Some people?
Some people?
Anyway, most everyone (with you and maybe Linkara being the expected few) agree that his multi-color coat is absolutely terrible. And it helped close-minded people like Michael Grade to move forward with its cancellation.
Furthermore, its so bad, its mere existence has become a joke in-verse. Both on audio and on comic strip, the only way the Doctor can defend the coat is to say that its exceptional "according to some alien species".
And the fact that you love this coat, but seemingly despise his outfit in
The Magician's Apprentice, is both baffling and confusing.
Again, that's your opinion. I love Attack of the Cybermen, its one of the strongest Cybermen stories I've ever seen (and I've seen all of NuWho's stories, Tomb of the Cybermen, the Tom Baker, Colin Baker and McCoy Cybermen stories, and Earthshock) and I find Vengeance on varos to be fine, but a bit of a step down from AotCM and The Two Doctors. The Mark of the Rani is also very fun, although not quite great admittedly.
Fan consensus has
Vengeance as Six's best story, with
Mark of the Rani as a forgettable story at best, and
Two Doctors as a weak effort by Holmes.
And I like
Attack, but it is heavily flawed. I will say this, though - its better than almost all of NuWho's Cybermen stories. Sadly.
To me, Ainley is The Master. When I think of the character, I think of Ainley. Delgado was also quite good, but no one will match Ainley to me.
Au contraire - Delgado's the only completely characterized Master on-screen, whose relationship had some certain depth with the Doctor and who wasn't just an actor acting hammily for a living. He gave his best to make his Master believeable, and often carried really weak stories with him (
Time Monster is worthy just for him).
Best after that? Well, Beevers from
Keeper of Traken and his audio stories, who's simply amazing to listen to. Alex McQueen, also audio, is amazing as well. And Missy works well for me, too.
Being a pale imitation of the 2nd Doctor is still better than acting like Delgado's Master if he was about 10 times more psychotic.
Delgado's Master? Seriously? He's a darker Doctor, sure, but he's still the Doctor - with a meaner streak than anyone since the First one.
You know why? Because of Six's sacrifice in
The Brink of Death. Hah!
Well, since you're the one who keeps declaring things "objectively" bad, while obviously having a lot of hatred for the same stuff, my questioning of your word comprehension stands.
Do you live under a rock? Its not my opinion - its consensus. As in, collective opinion. Get it?
The Two Doctors is my favorite Robert Holmes serial, outside of possibly Talons, so we definitely disagree on that.
Its nowhere
near his best serials. For one, the dialogue isn't as sharp as usual, and the Sontarans are a touch silly in it.
The 6th also wasn't really mean, just a bit cantankerous. I like him being more prickly than the blandly nice Davidson. He was argumentative, but honestly it never bothered me, either. I'm sure Big Finish turned him into the 5th Doctor with a fancier coat and different hair or something, but in canon the 6th Doctor's personality was fine, except for his very first serial.
Given how you've never heard of Big Finish, your opinion holds no water. He's mellower, yes, but so was he in season 23, and he was superb there - better than he was in 22.
And for the last time, Big Finish material
is canon. Its always been, given how BBC officially works
with BF, and they carry licence from them. And since
Night of the Doctor, its more than mere speculation.
