As far as i have seen the episodes so far.. its ok only, nothing that notable or noteworthy i care about. The characters are mostly devoid of charisma, i had some hopes for the emperor but i lost interest. Maybve ill return for the last episode, but theres better sci-fi out there i like.
The changes, BTW, caused a lot of holes in the plot. They are sent to Terminus via "slow speed" (which still covers 50,000 light years in 900 days so it is still FTL) because the Emperor doesn't like for the Foundation to have hyperspace technology. Even if we ignore how stupid this decision is (just make a law which says that if someone returns he is to be executed immediately), sending them to Terminus with a fleet of Imperial ships and then leaving them there was not in the cards apparently - not to mention how a foundation meant to collect and preserve all human's knowledge so to shorten the interregnum after the fall of the Empire will have the blueprints of hyperspace technology among the first items anyway.
The Empire, given the current situation, doesn't have basic anti-terrorist measures in place.
If you want to defuse a crisis, arresting and killing diplomats is not the smartest thing to do.
The Foundation does seem forced to decide "what" to preserve. This was never a problem in Asimov's novels. Even when they were written back in the '50s it was assumed that a whole planet and technologically advanced storage methods would be enough to store everything. That was not the problem the Foundation had to face at all. And why, BTW, scientists and mathematicians should debate if save the knowledge of math in base 12? It isn't that you need a supercomputer to do it: Wikipedia is enough. The whole scene is an excuse to have a young black woman patronising a reunion of scientists.
A colony ship hasn't a fleet off ground vehicles for when they arrive?
Anyway, even the basic plot goes off the rails by the end of Episode 2, and by Episode 3 it has become its own (boring) thing (Salvor Hardin is not only race/gender swapped but directly not Salvor Hardin at all). I don't think I'll bother to watch the rest.
