Agreed that Connections 2 and (especially) 3 were pale shadows of the original series.
However the related The Day the Universe Changed, which took a slightly different conceit (the episodes aren't necessarily linear in time) and focus (science and philosophy rather than technology), is excellent, and I'd put it right next to the original Connections series.
(There is, it turns out, a fourth season of Connections, "Connections 4", released in 2023 on Curiosity Stream according to Wikipedia. I've net seen any of it. It consists of only 6 episodes. <https://en.wikipedia.org/wiki/Connections_(British_TV_series...>.
