I remember the final days of DS in 1971--and yes! I did care about Catherine and Bramwell. I also recall that on April 1st (the show's final episode was on April 2) I told my mother (I was 12 years old, thank you very much!) that DS would not end and it was all an April Fools joke!
Okay--I was wrong.
Now, about the end of 1840, or Barnabas' and Julia's final scene:
[spoiler]In hindsight, upon watching show # 1198 several times over the last few years, after returning to 1971, Julia and Barnabas have the following exchange:
JULIA: "We changed all of their lives by being in 1840."
BARNABAS: "As well as ours. Think, Julia, think back to 1840. Those stairways are likely no more. Desmond has probably destroyed them by now."
JULIA: "We'll never forget any of them, Barnabas."
BARNABAS "Never."
And they leave the drawing room.[/spoiler]
As I said above, in hindsite, this exchange solidifies (for me) that Julia and Barnabas have put all their past conflicts behind and will move toward their friendship--and more. And it seems to me to put a "button" on the modern story lines, even without some of the resolutions we would have liked to have seen. From what I recall about conversations with Keith Prentice nearly 20 years ago, the show had been given notice of cancellation well enough in advance of the end of 1840, and the 1841PT storyline was a way to give Frid what he wanted (playing a different character), and a way to end the show without leaving the viewers hanging about the 1971 story and characters and resolution to their stories. (Personally, I am satisfied with that final scene in 1971 with Barnabas, Julia, and Eliot and Liz. I don't recall what I thought about it more tha 30 years ago. . .)
That's my 2 cents worth....
