I think it really goes without saying here that
Ghost in the Shell is one of those shows that is a masterful blend of visuals and psychological examination. In its very essence,
GitS showcases the interaction between humanity and robotic life and utilizes different aspects in the narrative to portray them through different means. Not only does it manage to bring up questions on the very definition of “life,” it also manages to show the complexity of how humanity attempts to define life within a world where people are able to seemingly exist physically and psychologically.
2nd GiG is easily the most fully-realized vision of what the franchise has to offer, since through its combination of episodic stories and overarching plotlines, the series fully gets to explore its vast world through many avenues wherein all its factors are put astutely into play in the narrative.
The central theme of the series revolves around the concept of the stand alone complex--which to put it simply is an incident that occurs when a bunch of stand-alone events appear to be working together in one complex operation. Season 1 depicted this with the Laughing Man case, in which it focused on portraying a series of incidents which initially appear to all be connected as the work of one criminal, but ultimately turns out to be a series of unrelated incidents by anonymous individuals. Season 2 takes this concept even further, in which the show broadens it in scope on a socio-political level--wherein it mainly focuses on the makings of ideological beliefs that in turns forms a revolution with Japan in the centre of it all.
While Season 1 put into limelights the effects of technological advancements, the usage of internet and consumption of information had on society as a whole, Season 2 expands on the concepts of networking and communication heavily, wherein it creates an extreme version of the stand alone complex. Meaning as information is dispersed throughout the net, it either degrades in quality or is deliberately altered and becomes a mass consumption by people which in turn leads to a state that the show calls synchronization for each individual person--meaning it renders the term "individuality" an illusion. Due to this process, people can be easily dissuaded to form similar beliefs / attitudes, which is the method that is used in the show to instigate a revolution. The concept is something that could be applied to the group Anonymous--which operates on ideas rather than directives, though in GitS case it is put to the extreme.
Thus we come to one of the major reasons why I truly love this franchise; it treats the viewer as an adult who possess a level of intellectual maturity. GitS is a show that has a clear grasp on its concepts--everything from psychological to political ones--and knows how to write the story and not simplify them to the viewer. While I understand the necessity for it--having to create a superficial representation of something more "complex" so that a large audience as possible can appreciate the medium--ultimately it is something that I loathe and more often then not the show suffers from it, and makes the story either a lot more simple than it comes across or just fails horribly. Thankfully this is not the case with GitS, since it expects the viewer to be educated enough to understand what the show delves into. The show does suffer a bit from trying to come across as a bit too "presumptuous", since it has a certain tendency in wanting to explain rather simple concepts as unnecessary complicated just for the sake of being more intellectual. This is thankfully a minor annoyance within the narrative, since one can grasp the core of the story just fine, but is still dumb in its own right I find.
Something that I found that 2nd GiG improved upon was its execution when it comes to pacing and dispersal. This applies from the main narrative to the actual combat that transpires within the show. Each aspect of the plot is very clearly covered, used and acted upon. Each element of the story is involved and well thought out, especially in relation to other elements. Almost every action sequence is well choreographed and acted, which allows the viewer to get a good scope of where the fight is taking place, what’s at stake, who is in control, and what each move could mean for the characters. The show features a vast array of characters, and most of them get a surprising amount of characterization, which is not excluded to Section 9 alone. All these factors complement the show and makes it an enjoyable journey on so many layers that you can't help but appreciate it all.
