Ghost in the Shell remains our most challenging film about technology
In fact, I would argue that Ghost in the Shell's entire franchise remains the most intriguing and exciting science fiction media about networked technology.If you have never seen the 2-season TV series (and 3 additional films), "Ghost in the Shell: Stand Alone Complex" (https://en.wikipedia.org/wiki/Ghost_in_the_Shell:_Stand_Alon...), it is by far the best contemporary outlook on near-future internet technology still. Black Mirror is up there, but I think that Ghost in the Shell: SAC presents this cultural criticism in a much stronger (ie., less unhappy) tone.
