A random bunch I loved straight off the top of my head because I can't even.
Starsky and Hutch, Hlll Street Blues, Fawlty Towers, Twin Peaks, Blake's Seven, Babylon 5, Cheers,
I hardly saw any TV in the 90s though. Caught up with some later but missed out on the big shows from that era e.g the X-Files. I could never get into them later.
