I finished my rewatching of UFO last night and it is still a 'good thing' - I'll probably do it again in a year or two. Highly recommended.
Some things stood out in the predictions of the future, even though it was set 40+ years ago, in the early 1980s. There was a great reliance on computers, of course, but they still ran on magnetic tape - sometimes even on paper tape - and the output was produced by golf-ball teletype printers. In one episode, an urgent report was delivered and included sheets of carbon paper. Screens were still all CRT, which, to be fair, they still were in the 80s.
There is a brief discussion about racism in relation to a promotion - and a reference is made to the fact that it had largely died out 'five years ago' - i.e., 1975ish...
There was a huge amount of smoking, even on Moonbase - and occasional gunfire within the pressurised structure, this seemed a bit iffy.
A lot of the cars were gas turbine powered, with powered gull-wing doors and the UK was driving on the right by then - but nobody has repainted the road markings.
There is an untethered spacewalk, which would have seemed almost ridiculous in 1969, surely.
There seemed to be a huge advance in psychology and 'mind control' in various forms.
The aliens, despite being able to fly across the galaxy, seemed to have personal weapons based on the technology of the Sterling sub-machine gun. This was despite their vehicles seeming to have powerful laser weapons.
There was very little differentiation in gender roles - even extending to women in string vests on the submarine, but there are continual, and possibly tongue-in-cheek, requests to women to get chaps a cup of coffee.
Some of the episodes are a bit 'hard' and would not have been regarded as "kid's TV" at the time, I suspect. In one, a woman is trapped inside a torpedo tube on a sinking submarine - and it is not nice.
I have now moved onto a rewatching of The Prisoner again. I do two or three episodes a week, rather than 'binge-watching'. I'm hoping this will help improve my resistance to the cat's control techniques.
