i saw this series on pbs in 1980 in college and i still can not get it out of my head and although i have never seen it since. i remember every cast member (the casting was perfect and as mentioned in other comments) and the design and the lighting and and of course and the story and which is by itself is enough to keep you glued to the set. probably the best tv series i ever saw next to the original roots.
