A bit wordy and dry, even dull at times at times (especially early on), but also full of ever more interesting insight and theories by writer/host Jacob Bronowski. It reminded me of nothing as much as a really interesting illustrated college lecture series.
The series is in 13 parts, each covering a different key step in the development of civilization. A few of Brononski's theories seem a bit stretched, or even wrong headed, the visual style is dated and the effects less than impressive, but that doesn't mean the show isn't interesting, thought provoking and occasionally quite moving -- especially as the series goes on.
I don't feel I need to ever re-see the earliest 4 or 5 episodes again. They feel pretty pedantic and straightforward, and there wasn't much I didn't find familiar.
But the the last 4 or 5 episodes are incredibly clear explanations of the often complex and confusing world of 19th and 20th century science, mixed with quite touching observations about the role of science in a bigger society, its poetry, and the way it feeds humanity' soul.
A strange series - it starts out as fine but nothing special, and ends up somewhere quite powerful.
