A TV show made before 1990 that you think has aged well?

I'm a huge fan of I, Claudius and have watched it many times. It's great to this day.

Some great 1970s British miniseries! The Six Wives of Henry VIII, Elizabeth R., Edward the Seventh. I absolutely think they hold up.

Upstairs, Downstairs.

Twilight Zone - Great Pick!

Shows such as Star Trek and The Andy Griifth Show while I like them and consider them entertaining I would also consider them dated. Things that jump out me lately with ST is the show is too Kirk-Spock centered in the mundane tasks aboard the ship. In Tomorrow is Yesterday Spock relays the countdown to beam the 1960's people back to Earth when in reality that would be most imprecise compared to a computer or two performing the same task. I know the first season was rushed but the dialog is very clunky compared to a lot of later SF efforts. I chalk this up to being the first time somebody had to seriously think about a situation and people such as what ST was set in. The Andy Griffith Show had too many stories where Andy bails Barney out of a jam so Barney never learns the lesson he needs or starts on a career he can actually do competently. I still like those two shows but can see them for the time that they were made in.

I recently binge watched 21 Jump Street as I never saw every ep the first time around. I got up to the end of the second last season. I could see it starting to die there, I haven't done the last season yet as Hanson and Penhall leave and I am not that interested in Hoffs who becomes the last original cast member.

I thought it held up ok very 80's which was cool. A bit hokey at times, the 80's was all about the "Very Special Episode" which was almost every ep with Jump Street.

Surprised no one's brought up Mash.
