Magnus, I get it. We all get it. You don't want to see a new DS unless it is a continuation of the old. Does it really bother so much that other people simply disagree and would like to take a trip in the imagination down a path not to your taste?
And for the record, I never mentioned "TREK without Spock" but "TREK without Vulcans and Klingons" because in terms of the TREK universe those are iconic. Just as in DS the Collins family, the Collinwood estate, the sense of the past reaching out to hurt or shape the present, etc. are iconic to DS. On this very board you've complained about ideas for a DS series that lacked the things that made DS itself. Others have pointed out other iconic themes--the cursed love triangle that transcends time, the governess at the heart of mystery and desire, the protection of the Collins Heir, etc. It would be like STAR WARS without Jedi Knights (as opposed to specific Knights), or Hercule Poirot stories set in the modern era (been tried, didn't work).
On another note, I was generally thinking of (for lack of a better term) television actors for a television series. Also, it seems to me that redoing a show like DS adds a factor which is lovely in theatre--that is, we get to see different actors do their takes on the same part. I am one of over a dozen people I have seen play Malvolio from Twelfth Night live, and it is really lovely/startling to see varying 'takes' on such a juicy role. Ditto thousands of other parts. I have seen four different men play Barnabas Collins (five if you count the Big Finish audio dramas) and will almost certainly eventually see two others--Alec Newman and Johnny Depp. I quite like the idea of seeing still more.
How many ways are there to adapt Dracula? Look at Max Shrek, Bela Lugois, Carlos Villar, Christopher Lee, Denholm Elliot (ok, that one is rare and obscure, but worth the look), Marc Warren, Louis Jourdain and Gary Oldman. Or any of the many adaptations of Jane Austen novels. Take a gander at Lawrence Olivier's film of Henry V and then at Kenneth Branaugh's version of the same. Rent Al Pacino's Looking for Richard then rend Ian McKellan's movie Richard III.
Mind you--here's a fun idea. What if a new DS weren't on television or the big screen? What if a new DS were created for the web? Look at Dr.Horrible's Sing-A-Long Blog or The Guild or even the online audio drama Wormwood (a town that frankly makes Collinsport look a little bit like Mayberry). How long before technology allows us to to even more amazing things with seemingly-ordinary desktop computers?
