The show had good stories and tried to have something for everyone - it's TV after all - and not take itself too seriously. Kookie was there for the kids and, along with Roscoe, brought colorful comic relief. In one episode, Spencer arrives in Hong Kong and passes a rickshaw-hop (Byrnes in mufti) running a comb through his hair. It was a fun show! And the West Coast jazz they played at Dino's was very hip and still sounds great.
But at the heart of the show were Bailey and Spencer and the cases they solved. And these remain on a par with the best of episodic TV. The two characters work, the scripts are fairly thoughtful and bring in good characters. Zimbalist and Smith were spot on. Terrific TV.
