Took me forever to find a copy of this book at a bookstore, but when I finally did I plopped down for three hours and read it right through. Admittedly I did this because the $15 price-tag for this novelization is utterly absurd, but also because the book was really quite a lot of fun.
I pick novelizations, generally, that are of high action films. My main attraction to the genre of novelizations is that the authors have a duty to present the overwhelming physicality of film in written format, and to do so with excellence and thrill; it's a style of writing I have seen butchered to great failure in a number of novels, but with novelizations the quality ratio remains generally high and inspired.
It's no different here with Ghost in the Shell; the action, explicit and vivid scenery, and sci-fi tech devices are all written with great speed, fluency and excitement. Although GitS has lengthy origins in images (beginning as a manga, then the masterful '95 film, followed by various other manga/anime adaptations, and then finally this 2016 film the novel is based off of), there is still room for visualization of all of the elements which the story affords through written form, and it's great fun to let the mind construct and detail New Port City and all its cyberpunk craziness.
In terms of story, the '95 film remains far and away the top-tier, with this modern adaptation particularly ruining the ending unfortunately, but overall the stories are roughly alike and this provides an engaging narrative that satisfies enough on its own; but certainly, it is the scope of technology and existential idea which will prove the fuel for your attention.
It's good solid fun. The novelization is very light on the Japan locale of it all, opting instead to focus more on modern advertising and architecture rather than delve/settle into cultural specifics, and I'd say that's good reasoning in regards the book's (welcome and appreciated) lesser pages and tonal rhythm.
Worth reading for any cyberpunk dork. And yes, even if you've experience with prior GitS narratives, this one is worth checking out.
