I've been watching this. I agree with your points about Blade Runner and the visuals but I'm finding it entertaining enough for TV science fiction. I can't comment on the book as I haven't read it.
Generally TV and film science fiction is rarely up to the standard of the best books. However, if anyone is interested, by far the best TV science fiction I've seen in a long time is
The Expanse. I'd read all six(!) novels before seeing it (there is now a seventh - nine are planned) so I'm not sure how it would play to someone who hadn't.
BTW links that end in a bracket get broken if you don't put them in [url]...[/url] tags, here is a working link to the Altered Carbon TV series:
