Babylon Berlin Season 3 excellent in many ways but sure demands close attention!

Babylon Berlin, Season 3, in an odd way, reminded me of the great British series, The Crown: The amount of money and the creative energy to replicate what I will take to be the look, sound, sense of Berlin in 1929 down to the smallest detail: clothing, decor, street scenes, autos, implements (e.g., a 1929 telephone), music, entertainment, clubs, bars and dives,  prisons, hotels, government bureaus, the list could go on). In other ways BB is its own series entirely (with a nod to Berlin Alexanderplatz, a little earlier I think but the same locale), and for the most part exciting and engrossing in every episode and enormous in scope. Particularly in Season 3 we see the political forces coalesce, as the Communists face off against the National Socialist Party, and we know who's going to win out on that one - this series in S3 is really about the rise of the Nazi power. But there are many other plot strands in S3,  probably too many - a film financed by two sometimes-rival gangsters that leads to the death/killing of 3 of the star actresses; the trial and approach to the execution of Greta, convicted of planting a bomb in her employer's house killing him and his daughter - but who put her up to it?; a police investigator who goes off the rails; most of all the continued saga of Police detective Gereon Rath (Peter Kurth) and his complex relationship w/ his former sister-in-law whom he loves - and I'm leaving other aspects out such as the stock-market crash and the rise of the Hitler youth group and scenes of the gay Berlin subculture. So much that I honestly could follow maybe 80percent of the story line if that; for some that might not be a flaw; perhaps my concentration isn't the greatest of maybe the whole season demands a 2nd viewing (yikes, I forgot about the ongoing experiment to remake a human psyche through analysis and hypnosis!), so be warned, you have to give a lot of attention to this season to figure out how all these plot strands entwine and co-exist. I really think better plot recaps at the outset of each episode would help. My only disappointment, however, is the failure to develop the character of Charlotta Ritter (Liv Lisa Fries), who at the end of S2 was poised to become a full-fledged police detective; in this season, she never really takes the lead on any case, though it's clear she's the smartest one in the room. I appreciate that the season shows the sexism that she's up against, but I wanted her to have a stronger role as a protagonist and less of one as a victim. (Also, wish they'd had Kurth dance again.)
