I recently bought the Blu-ray set of the series. Hadn't watched it since its first run in the 80's and never saw it in reruns. I was not sure how well it would hold up. It holds up very well after the first 5 or 6 episodes I have watched. Very gripping with a stylish film noir vibe. My wife never saw it back in the 80's and she loves it.
Glad she likes it! It is definitely like going back to some of the best times of my life when watching the series.
