Second half of the foundation story just missing in action, a matrix of characters from different eras, Bel Riose brought in prematurely presumably as an antagonist to Hober Mallow, the mental chess deprecated in favour of Star Wars type action
While I think there was some wait and see with S2E3, this one (S2E4) just lost it's way, even if it was an attempt to patch together a gaping hole in the story.
So we are moving through Foundation & Empire to get to the Mule & Second Foundation, but the influence of the third factor in the psycho historical expansion of the foundation, The Traders, of which Mallow and Danvers were pivotal characters, appears to have been abandoned.
I have to observe that the subtlety and mystery in the psychological build has been sacrificed to cgi and action, so the story layers & reveals are sort of too obvious. Not underestimating the capacity of viewers to absorb and follow a complex plot is something that Scandinavian & British writers have often done well in crime & mystery thrillers (eg The Bridge)
Foundation could have reached for the heights that "The Expanse" achieved, but I grieve for it's likely fall, just like Empire. A mish-mash of Foundation & Foundation & Empire.
