Like Alasdair, I love video archaeology of this sort. I have some half remembered lost series of my own from childhood. Naturally, the most creepy ones are the ones that still make me want to seek them out and find them today, as those are the ones that tend to haunt one. Sometimes, I find a needle in a haystack through the scavenger hunt, and rediscover how weird it really was, realizing that my childhood memory was not faulty after all. It really WAS that strange. But some items have sadly remained lost in time.
Oddly, our supposedly more sophisticated modern world actually both broadens and limits what one can expect to find on TV now. When I was a kid, our local public broadcasting occasionally had some nudity on some shows from overseas, and some domestic art shows, but now pixelates such things to obscure it. Not saying whether that is good or bad, I don't know, but what changed culturally since then such that we actually censor things more now in certain ways? Rated G cartoons from my childhood also had things like mild cursing, and even body counts, that I don't think you would see in a kids film today that managed to get a G rating. Again, what changed?
This is partly what makes video archaeology so fascinating though, as the past often holds things we wouldn't allow for today in contexts we would now consider odd. Likewise, the MC of this story wonders if something bondage related could have somehow made it into a 60's TV show.
I like how the characters in the story are at first dismissive yet still curious about the show, but then are drawn further into its mystery. Such is often the case upon examining again something that you thought you understood the first time, but later realize, perhaps with the benefit of more experience and a more patient mind, may have had more to it after all.
That said, like with the creepy pasta stories that led to stuff like Candle Cove, the challenge of these kinds of tales is to somehow end the thrill of the archaeology chase by taking the story somewhere both interesting and conclusive, and I think this one has more mixed results there. Admittedly, it's a hard thing to pull off for this kind of story, but I recall at least one time when it was done, with a story about an old children's show, (not Candle Cove) that the MC had a personal connection to. Sadly, I can't recall the name of the story right now though. But wow, did that story have a solid set of twists and an ending. I realize that erring on the side of mystery can have its charms too. But I think it's good to strike a nice balance.
