The Empire part is basically non-existent in the first book, they changed a lot of what was there, and the whole clone thing is totally new. It would've been cool as its own IP, since it basically is anyway, but it's not Foundation.

And the Foundation parts were heavily changed. The whole format was changed, the story is supposed to take place over generations, navigating crises every 50 years or so, following new characters each time. I had to stop watching because it was basically unrecognizable and completely spat in the face of the themes of the book.
