I disagree. The original trilogy was one thing, but in the following four novels he really changed it and we are seeing those changes carried through. If you read the Foundation stories, each one really revolves around the actions of a handful of people who steer the galaxy in the right direction. Seldon is there all along with his predictions and twice Salvor Hardin steers things along. The Second Foundation is nowhere to be seen as of yet in this series and what we are seeing are the same sort of abilities the Second Foundation had. While the science of Psychohistory can only work when the people are unaware and can't predict the actions of individuals, Seldon's plan almost requires individuals to keep it on track. It requires a Second Foundation and a guide for it. In Asimov's books that guide was Daneel. I don't know if this Demerzel is that same guide. She might be. But I see that they are very much taking Asimov's writings and molding them into a feasible TV story. It is still very much Asimov's creation, though not his creation from the 1950's as it leans more to how he modified it in the 1980's.So Gaal has "magic" prescience powers and the plan depends on her - and also apparently Salvor who is probably her daughter developed from a fetus implanted into a surrogate mother? I don't think the people adapting this series have much of a clue about the basis of Psychohistory as described in the trilogy where it's humans in mass numbers that are important, not individuals. This show has now deviated so far that it is its own creature. It's not unwatchable but it's not really Foundation apart from the names of some of the characters and places.
