I'm not sure if I'll ever read the manga (I just generally prefer film to comics) and I'm pretty unfamiliar with Aria (although I guess I have a passing familiarity with gynoid fiction just from cultural osmosis) but I loved all the deep-fried Pre-Vapourwave 90's anime aesthetics combined with all the unsettling details. The way the show's directed reminds me a lot of Serial Experiments Lain and Kino's Journey, which are some of my favourite shows so I'm honestly kicking myself for not getting round to watching this sooner.
