What are your precise criticisms about the adaptation?

I am seriously unsure of whether I like it or not. Some ways in which I have gone back and forth:

- It's visually on point (I think) in conveying the vastness of Asimov's imagined Galaxy.

- The storyline is bent out of shape; but not enough to make it seem like a totally different series.

- Then again, Salvor Hardin's character and others are much more action-oriented whereas in the books they are depicted as thinking and strategizing a lot more (from what I can remember, I really need to re-read the books).

So I don't really have any substantive criticisms apart from a vague feeling of "this could have been better". Do you?
