Definitely dramatic and defintely 70's - enjoy.
I have the first six seasons of Quince and enjoy watching every once in a while. I especially like the episodes where he is solving a murder mystery. Toward the last few seasons there tended to be too much drama for my taste, so I do occasionally skip one of those "issue" episodes that became more prevalent in seasons 7-8.
Season three is prime Quincy and should bring you much pleasure. Jack Klugman is a walking firestorm!
I grew up watching reruns with my mom, so I purchased the S1-2 set to see if it held up to scrutiny and it did! I need to look up the season in which Quincy rages against punk rock (my favourite music genre) in an infamous episode. During the pandemic, my interest in revisiting old TV shows has been rekindled.
