Recently, Sky Television in the UK announced that it's doing at least two 60-minute new Blakes Seven episodes, as a relaunch of the immortal 1978-82 SF series. It's a retelling though, reintroducing Blake and crew from the beginning of the story. I'm utterly uninterested. That kind of series I see as being in competition with the original, a sort of attempt at a replacement (with those glitzier effects that people think are so important), and I like the B7 I have.
The first is the arrival of Victoria Winters, primarily because this was a truly original storyline. You can change all the names of these characters and toss them in a different series, while keeping the same storyline, but it would still be recognized as the story of Art Wallace, the first story of Dark Shadows: An orphan arrives in a small fishing town to become governess to the heir of a mysterious estate, a mansion filled with the secrets of those who live there. That's Dark Shadows no matter how you look at it.
