Honestly, the Eccleston/Tennant design is my personal, definitive version of it. Its never been bettered since, and quite honestly, the white original, especially in the '80's, looks... well, how can I put it? Fake, as is in, unrealistic that it'd have endured centuries of adventures as it looked.
Well, realism has never really been a consideration in
Doctor Who, has it? I just like the aesthetic, the white, roundelled walls and the hexagonal console with controls that actually look like controls rather than a half-melted junkpile. I mean, for my first dozen or so years as a Who fan, that simply
was what the TARDIS interior looked like, except in series 14.
Whereas the McGann TARDIS looks like a home, which is a valid interpretation. After all, it IS the Doctor's home.
That's a fair point. It's not so much the larger set I didn't like -- I just found the retro, faux-Victorian console design a bit silly. He wasn't H.G. Wells's Time Traveller, he was a denizen of the most advanced civilization in the universe. Okay, I get the logic from the modern series that that selfsame technology lets him make the "desktop theme" whatever he wants, but I prefer the console to look futuristic.
I think the current, Capaldi-era design does a great job of making the console room look like a home while still keeping it clean and high-tech in the way I like. I have a fondness for the simplicity of the classic console room, but the current design is probably the best it's ever had.
I also love the wooden control room from Hinchcliffe's last year. That was so awesome.
As you can guess, I wasn't crazy about it. Again, I didn't mind the overall set, I just didn't like how basic the console was. I mean, a shaving mirror instead of a time rotor? Come on, give me blinky lights and buttons and bits that move up and down!
Of course, that's the whole reason they built a new set that year, as well as the reason that they'd had no TARDIS interior shots at all in Tom Baker's first season. The prop and effects departments kept insisting the console was the other guys' responsibility and it led to all sorts of union disputes, so Hinchcliffe just avoided the issue by avoiding interiors altogether in his first season and building a non-mechanical console in his third.
Which made for a weird experience for folks like me whose exposure to the series began with PBS showing the Tom Baker seasons in the '80s. With one complete serial aired per Saturday night (cut into "movie" form), starting with "Robot," it was seven weeks before I first got a look at what was inside that blue box. (Of course, the beginning of "Robot" is itself a pretty weird introduction to the series...)
Like it or not, its part of the Doctor's central moral philosophy. That human ARE one of the greatest of races. And its always been part of the character, certainly since the Second. What the Fourth says in Ark in Space is a mere confirmation of the fact. Making him half-human relegates the Doctor's notion of humanity as hardly objectionable, therefore dishonest.
Yes, he admires humanity, but he never says there are
no other species in the universe worthy of comparable praise. Indeed, we've seen there are other species that he holds in quite high regard, including the Silurians/Homo reptilia, the Ice Warriors, the Ood, and others. That's the issue. With trillions of sentient species in the universe, past, present, and future, it's unreasonable and frankly quite racist to think that humans are the
one and only species worthy of his respect. So it makes sense that there'd be some reason why, out of all his most admired species, he chooses to spend most of his time with humans instead of one of the others -- even though humans are also responsible for so many of the atrocities he's fought against and he often gets quite angry at us. And it would certainly help explain that relationship -- his continued forgiveness no matter how we misbehave -- if we were family to him.
I'm not saying it's the only or the best explanation for that... just that, if the McGann movie had spawned a series and the Doctor being half-human had ended up becoming canonical, it would've made sense to me. It wouldn't have been my preferred choice, no, but if it had happened, I could've lived with it because it would've made a good explanation for that specific question.
