Well, not having seen season 6, I can't speak to anything that's happened then, but all I've seen in New 1-5 is building on what came before. That's what Doctor Who does.
Each Doctor adds a bit to the lore, and each creative team pushes the story along some more.
If they didn't, we wouldn't be heading toward the shows 50th aniversary.
Some changes were liked some, weren't, each new Doctor has been met with a mix of excitement/anxiety. I've been watching this show long enough to have heard a half dozen times how 'so-and-so is ruining it! this is the end!"
and yet, here we are.
and BG, gets no slack cut from me, 'reimagining' is every bit as lazy as whatever huge crime you are accusing Moffat of, Clara. Taking name recognition of something and then changing whatever you feel like is weak and done by people that want it both ways.
Make your own.
Didn't like it in that show, don't like in comic books, and didn't like it in the New Star Trek movie.
and this is a personal and petty thing, but ...Toasters...? Really? An alien culture nicknames the big, bad that is trying to kill them Toasters?
Did I stop watching before the episode where hot bread pops out of one of the Cylons?
