The main things I remember about Dark Shadows other than Barnabas were Angelique's eyes. They were absolutely hypnotic. And the episodes were done live, so it was fun watching when they made mistakes. I tried to watch it again recently, but just couldn't get into it. These days, if I'm going to rewatch a series, I try to stick with the ones done after 2010 or so because the toxic masculinity and patriarchy in the writing before then comes through loud and clear.
