Dragnet
I recently got a box set of episodes from this show. It had been hugely popular at the time, innovative, different....but it has not stood the test of time. Now you can see how cheaply it was made, with Joe Friday and his sidekick never talking to any other cops except on the phone, with a lot of dialogue replaced by Fridays' voiceover -- a good way of reducing sound synchronisation costs -- and the whole series with hardly any exterior scenes.
I found it virtually unwatchable.
Lady, I don't have the time....
