I'll add my voice to the consensus, ignore the part where it's connected to the books. It's a superficially similar story, but it has neither the purpose, storytelling or even plot points of the books.
What I find the hardest is that despite having a solid plot and concept to follow, the series has very weak story telling. It might be that I'm getting old, but I find the focus is more on eye candy and cool situations than on progressing the story and characters.
It has the feel of filler content to generate ad opportunity, or an illustrated podcast about someone who once read the books but has too much ADHD to be able to retell what they read.
That is also the vibe of much other content on AppleTV, so might be a conscious choice of which I'm not a target demographic. I'll be shouting at clouds about it though, maybe it'll slow climate change while I'm at it.
