Yes, but the material have been re-digitized because the quality IS better, judging from some illegal copies I found on the net(..). At least to 720p, I don't think its possible to do proper 1080p, you start seeing the tweening pixels then. But then again, resizing techniques have come a long way since..well, forever.
I've never seen/heard of a 720p copy of an Eccleston or Tennant production around. Which one(s) are you thinking of..?
As for upscaling, all of the BluRay upscales I've seen in my life were horrible. Oh, my, my eyes still ache at the thought of Blue Submarine 6... Was such a great show, and so proud of its tech advancements at the time (it was one of the first anime to (clumsily) integrate 3D), and the BluRay release is just a resized 480p. Really, I have yet to see a proper upscale that 'guesses' intermediate pixels instead of interpolating them. Any examples..?
Thankfully, not all re-releases are badly done. For instance, one of my favorite movies -- "Waga seishun no Arcadia" (I'm sure you saw it
as a kid) is absolutely stunning in its 720p remastered edition.
An example, the future episodes in almost every seasons 2005 onwards..always something about society that is brought up, often common themes in serious sci-fi literature/films(NOT the Star Wars/Star Trek stuff).
Star Trek is way more attuned with society issues than Doctor Who has never been, AFAIK.
I don't mean to say Doctor Who is not, or was never relevant societally. But Star Trek, while it came later, pioneered the whole concept of using alien civilizations to represent human dystopias.
And the brits do have advantage in this area, they can really combine that seriousness with goofy/dark humour. And if done good, even frightening so. A fav of mine in that respect is the movie "Children of Men".
I don't see CoM has having any kind of humour, but then again, maybe I never understood Cuaron's cinema... :lol:
(Come to think of it, maybe Little Princess was a parody, rather than an appalling travesty of a Disney-like adaptation of a nice, rough children's book. I could never have guessed that guy would go on to make CoM, Gravity and HP3.)
