I just finished part 1 and, well, I’m kinda disappointed. It’s not bad, I think it’s actually pretty solid, but compared to the book it’s much worse in terms of story progression and characters. Some parts felt really rushed. I didn’t expect it to be better than the book, but I still expected better adaptation considering that (at least as far as I know) it was well received and I knew that it didn’t adapt whole book so I expected it to don’t skip too much. Is part 2 any better?
It’s impossible to adapt, see all previous adaptations. I think you’ve pretty accurately summed up the shortcomings of the medium for that story. Watch the movie to marvel at the setting brought to life with a nice soundscape, ideally see it on a big screen. If you read the book you’ll have some attachment to the characters and universe anyway so pacing and skipped detail shouldn’t be too much of a problem for you. Just don’t expect it to be perfect. IMO the second part is a bit stronger, maybe because the scope is tighter.
