Look at what Apple did to Foundation... They cannot even respect their own classic...
I saw review saying "it's nice if not considering its connection to the books", i.e., by itself its quality is good. For how much that's true for someone, I guess it has to be discovered watching it.
I wager its harder for the writers to get the second partition down pat as they're still getting used to adapting a story that has to move quickly owing to the limitations of TV, but its clear they can write good material which the first partition makes clear. I think the first season will be rough for them but a second should be more promising as they should get a handle on working with a plot that spans space and time on a grander scale than Game of Thrones.
Which is actually what I hoped for, since a) the format of the books is impossible to translate closely to a TV show or movie and b) Asimov is definitely a bit high and low in his writing. The first two books of Foundation are amazing, afterwards it gets quite meandering.
My main criticism would be the mystification of Psychohistory, which is a very serious flaw, but I'm willing to overlook it due to seriously lacking good science fiction entertainment.
This is a nice summary of the underlying pattern of the adaption. If they actually understand the idea, and follow the spirit, I think it's not too hard to add concrete details that substantiate the show. It is this inherent desire to not describe science precisely, but deliberately guts the details and label liberal value onto it, that causes the whole detachment of form and spirit.
It's like having a Cheeseburger. Or a Banana. Not even an Apple.

But if you are a fan of the original story, it's a spit in the face of a masterpiece.
The title, names and arcs are basically used for branding.
It was predictable, the Foundation cycle is mostly dialogs spanned over hundreds of years. Little details is given to action, and characters, which are superficially developed and serve mostly the purpose of a vehicle for history, die of old age every few chapters or so.
Very hard to adapt, and pretty much impossible to make money outside of the show, with the face of your actors, by selling toys or pretty symbols. Also, good luck keeping hooked the general public. There is no focus on sexuality, little humor, hardly anyone relatable, they talk a lot then goodbye.
So they made it a block buster. It sure can work, but it's not Foundation.
In the first minutes it's already game over: they try to get you interested in the human characters in a book where the main protagonist is an entire galaxy over centuries. All named persons are going to die every 3 chapters, I get that you can't get ROI on your expensive hot actors faces, but that makes no sense for the material you work with!
There are some significant exceptions to this, however.
