I really enjoyed them too, which I guess I could have made clearer. I felt like my enjoyment was heightened by my knowledge and nostalgia for the books, but interesting yto hear another positive perspective without that aspect. I suppose what I’m trying to say is not that they aren’t or can’t be good, but that they aren’t and can’t be a faithful and complete adaptation.

The world building aspect is why I tend to think TV series are generally the better screen medium for scifi than feature film, having more space to explore the causes and consequences of a fantasy premise. But yeah, I love a spectacle. The setting and soundscape of the new movies are top. Like I can’t rember feelings like that in the cinema since Lord of the rings.

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.
