I have been watching or rather binge watching, the 1966 gothic soap opera Dark Shadows. It can be seen on Tubi TV. There is Dark Shadows: The Beginning and Dark Shadows (when Barnabas Collins joined).
The Beginning, pre Barnabas, is about mystery, secrets, eccentricities, relationships, with rumors and ghosts, secret doors, murders. It is a gothic soap opera that was recorded life on tape the week before it aired. So there is a sense of live performance with load of mistakes like the errant camera man entering the right side of the frame to set up the shot of Joan Bennett (Elizabeth Stoddard Collins) would enter the room. There are microphones entering the frame from the top or the side. There is the occasional background studio noise, or the squeak of a camera dolly as it backs up from the actor. Actors flub their lines. I heard in an interview that in one scene a page was missing. The actors sensed something was missing. It sounds like a mess, but it's not. It is, so far, over 100 on time live performances with little time to memorize lines and rehearse.
As I mentioned, it is on Tubi TV. There is also a DVD collection (126 discs, 9 episodes per disc, plus discs with bonus material), that is expensive, but I wouldn't say excessively expensive, about $3.97 per disc. When you do the math though, it is expensive. POINT IS ! !! ! Each episode starts with a recording of a chalk board with the show's name, recording date, air date, and number. I find those interesting as well. Sometimes one of the actors hold the chalk board. At one point, one notices the chalk board as been broken and taped together. Then around Christmas 1966, or just before 1967 New Years, they got a snazzy new board.
