I'm glad you discovered this and excited to compare notes with you on it!

As I say, I'm a big fan of DS, and though I haven't thought about it for awhile, a few years ago I was on quite an extended binge watching it. I started off with the very first B&W episodes when Vickie first arrives in Collinsport and progressed on up through the appearance of Barnabas and on up into the color era a ways.
I have to say that I prefer the early episodes for their subtle, dark, mysterious nature. Later on, when they started throwing in all kinds of monsters right and left, it got a little silly and I lost interest (though it took awhile for that to happen). I may continue on with those at some point, regardless.
My favorite characters are probably Elizabeth, Roger, Barnabas (of course), Vickie (whom I have a serious crush on), Maggie Evans (whom I also have a crush on), and Burke Devlin. Actually, my favorite "character" is probably Collinwood, that fascinating, massive, dark shadowy place.
Yes, the acting is over the top (and with frequent bloopers—it was recorded in one go every day), with scripts that were obviously produced in a rush from day to day. And the plot can be incredibly slow-moving—which my wife complained about when we were watching it together; I don't mind, though, and kind of like that aspect. It's the atmosphere of the show that's great, as you pointed out. It's a show that really does capture the imagination, doesn't it?
So tell me a little of what you've seen so far. What's happening?
