I think most DS fans watch it for the good writing, acting and atmosphere and forgive the bloopers, not delight in them.
That's most certainly the way I feel.
It seems in the 80s DS had this reputation amongst uninformed journalists for being "campy." Lately, this notion has started to change a bit, and "horror/fantasy" magazines and websites in particular seem to be giving DS the place it deserves as a groundbreaking and legendary show in the genre DESPITE the mistakes.
It's been amazing how much respect DS has been receiving in print and on the Web in the past three years. Not amazing because DS doesn't deserve it - it truly does - but because, as you've said, the '80s and even into the '90s all we invariably read in nearly every article about DS was how "campy" it was. And what was more unfortunate than that was how the writers of said articles backed them up with passages from some of the PomPress books that, shall we be kind in saying, made it seem as if things actually happened on the show that never actually did (like, for one, the story about Terry Crawford supposedly [spoiler]bouncing off a matress and back into frame during Beth's fall from Widows' Hill[/spoiler]as if it actually went out over the air that way, which, as any DS fan who has seen the episode in question knows, it clearly did not
). But then, it's certainly not the complete fault of the writers who trusted the info in the PomPress books. After all, so far as they were concerned, they most likely thought they could rely on the PomPress books because they were unaware of the, shall we say, certain inaccuracies and misconceptions the books all too sadly contain, often times in chapters written by the DS actors themselves.
