This is obviously going about the golden 80s
I would say Knight Rider, Airwolf & The A-Team, basically some kind of renegades
On the other hand maybe that's the reason i did not like the police shows CHiPs, Starsky & Hutch or Hawaii 5-O
This is totally dependent where and when it was aired
e.g. i saw Miami Vice super-late, because it only came super-late night on public tv, but when it suddenly aired at prime-time on private-tv it was now available to a whole new group of viewers and had stellar ratings ( everybody was perplexed )
If the 90s are included:
X-Files was also great but i think i stopped watching religiously after season 4 or so and only watched the twp-parters from then
If StarTrek TNG and DS9 are SF-drama, then i add them
Babylon5 the SF-DRAMA of all SF-Dramas
But i have to add: old is a relative term
the Battlestar Galactica Remake is now 20 years old!
Star Trek TOS was younger when i first watched it mid-80s as a double-pack with Dreaming of Jeannie
