I vaguely recall watching a few of these when it first aired and then finding it via some dvd/streaming service years later.
The plots and direction were solid although there are spats of weakness. Nick M was an excellent actor and there were always good supporting actors.
The music is one of the things that truly made this outstanding. The songs I believe were originals and always fit the story very well.
In some respects this reminds me of Person of Interest without the side-kick and the dog, Bear, only had one visit being a cat called Orange Blossom.
For a show from the 80s it was really good.
