The show was absolutely amazing when it could follow the books. The definitive show everyone talked about. The moment the books ran out it started to go downhill. And when they couldn't easily extrapolate from the books the show fell apart completely. The showrunners and writes for the show weren't good enough to make Game of Thrones on their own. No offence, but that takes a lot of skill and luck. They were good enough to adapt it though.
There's a reason why people love the Foundation. Why we read the books almost 80 years later. And it's not because of the title or character names (which is all the Apple show keeps).
The creators of this show are extremely arrogant. They think they could have done better than Asimov given the setting. So they threw away the thing people loved and replaced Asimov's work with their own. Well, clearly they couldn't do better. The show is a boring disjointed mess of random scifi tropes.
Hardin is now a "warden"!? Literally, the character with one of the most memorable sayings in all of literature "violence is the last refuge of the incompetent" is now all about violence. That's nothing less than a betrayal of the source material.
