Jack Warden was great in this series. It's like it was the part he was born to play. Sometimes instead of dialogue he would make a grunt which conveyed so much more than words. He would know that the other person was lying or deluded, and the grunt would say it all. I also liked the way he would, let's say, steal a car to chase the bad guys, saying "What could possibly go wrong?" Something always went wrong.
Jack Warden's son in the series was good looking, and of course a lot younger, but if I had a chance to pick one of the two fictional characters as a romantic interest, it would be Jack Warden. He had that old-fashioned kind of masculinity, and a more intersting persona.
I loved the show and it would be great to see it again.
