I started watching, because I was lazy and Prime recommended it, and stopped after about 20 minutes in. My impression in that time was "Rebel teenage girl outsmarts everyone in overdone and ugly CGI but we've added something about neuro to make it look sci-fi". It felt like the Hunger Games, but less realistic. I did not know at the time it was written by Gibson, who I admire as an author, but also it did not come to my mind that it could have possibly been written by him. Is the screen adaptation so different from the book, or did they add filler to make 8 (or more?) episodes?
