Marcus Welby.... 
QUINCY.. 
Marcus Welby.... QUINCY.. Loved Barnaby and Quincy both as a kid. Don’t forget William Conrad as Cannon.
While Quincy was cool on a CSI level, it almost always seemed like he was on a mission to get more government control/intervention (rafts on airplanes, drunk driving laws, etc...) not more personal responsibility. Of course, as a kid, I didn’t know any better, I just liked the show.
NO QUINCY.. that rotten SOB was as anti-gun as it gets. That is an immediate DQ from being conservative.
As much as I like the show, I don’t think you can include ‘Quincy.’ As the series dragged on, it became more of a platform for exasperated sermons by Quincy, usually along the theme of ‘so, it’s profits over people, I can’t believe this!’
Basically, whatever whim caught the attention of Klugman became a story idea. The most notable (and laughable) is the notorious episode about ‘that punk music,’ that was driving kids to self mutilation and suicide.
