Like most of the rest of you, I enjoyed the brother Day/Dusk/Dawn plotline. But damn, they missed on everything else so hard. I don't know how you could read the books and get that script, unless you just said screw it, let's do the exact opposite.
For example, the way it came across in the show, Seldon predicted that Salvor was supposed to find the invictus, which would unite the outer planets. What would have happened if the defense system blew Salvor and the Anacreons up? Considering how close they all came to dying again and again, Seldon's whole plan hinged on some highly unlikely outcomes. Which is the exact opposite point of psychohistory - that human behavior in aggregate is predictable and that certain events therefore are highly likely to occur within a range of dates. Nothing about Salvor's story was likely. It was all individual, unpredictable heroics of a single individual that has the ability to see the future.
There's nothing wrong with that story per se, it just completely contradicts the whole premise of Foundation and is honestly not as interesting. Especially because now there is no real basis for the Mule to be a game changer.
I know I've already complained about this before, but for a big budget show to miss that badly is pretty frustrating.
