I totally had a teen crush on this woman after seeing this series.
I have this show on videotape somewhere still, complete with the hand-drawn logo on the label. I should rip it. I was 16 and very impressionable when I saw it. The marketing/promos for it were indeed excellent, totally created the right atmosphere, and might be why the miniseries did so well but not the series itself. My friends asked to borrow it at the time.
This and Knight Rider are my two biggest 80's TV memories. They probably both would look cheesy as hell now, but at the time they were very atmospheric.
