Just finished it - I don’t usually watch that much telly. I think the final two hour episode is where he starts to pull various strands together - obviously ideas about the individual and whether individualism can exist or win out, corruption, the failure of revolution, the inexorable power of capitalism, the elites and possibly their inability to maintain control. It’s also rather sad for the greater part because it’s full of stories of those ideals are lost or they themselves become broken and lost.
