I have been watching Dark Shadows, the gothic soap on DVD. In my younger days I watched reruns of it on my local UHF station and loved it. Its very fun to watch again. It holds up pretty well, and IMHO it was a trailblazer for later horror in TV and movies. Like many shows of that era, it clearly did not have a lot of budget for sets.
It is fun in that it was done sort of as live theatre in that video tape edits were expensive and hard to do. They just kept going over all sorts of blown, forgotten lines etc. The cast were excellent at keeping going no matter what.
One of the original actresses, Kathryn Leigh Scott, is now a publisher and writer:
