Well, why did I watch that? Because back then we basically had only 1 tv set and my Mum tried to never miss an episode. :) So it was either Knots Landing or... no real alternative. :)
In a way it's the "Desperate Housewives of the Eighties". They all live in the same street (cul-de-sac), they've all got their problems and secrets, people get killed/murdered, etc.
I would love to see it again just for the laugh. :)
