When I was a kid, I remember watching:
Gilligan's Island, The Munsters, I Dream of Genie, F-Troop, Medical Center, Marcus Welby M.D., S.W.A.T., The Rookies, Streets of San Francisco ... to name a few.
I was quite the TV addict.
I don’t find the production values cheesy. You can keep the sets simple like “The Honeymooners”, or put a lampshade on it like Burns and Allen. Good acting is more important than modern production values. Gilligan’s Island worked because of the chemistry of the cast, and that even characters that shouldn’t be so likeable(the Howells) remain somehow endearing. Perry Mason holds up well today. Great cast. Tight writing.
Adam-12 was brilliant. It shows how criminals should behave when they’re approached, questioned and/or arrested by the police. It shows how police should behave in the course of doing their jobs and the importance of knowing their jobs in the first place. It also shows how law-abiding citizens should behave when they deal with the police, and it even shows how not to behave. As a nice side show, there are classic cars all over the place!
