I). Plot Structure/Execution- GITS SAC has two types of episodes-
Stand Alone Episodes and Complex Episodes

A) Stand Alone Episodes- They can be effectively summed up as being double-edged swords. Ghost in the Shell feels like a lived-in world, as the worldbuilding is intricate and meticulously done. Perhaps the best I have ever seen, which is great and the Stand Alone episodes are responsible for creating this vastness. HOWEVER, the overall quality of stand-alone episodes greatly varies and even though they are extremely intelligent in nature and explore a wide range of topics, they do tend to deviate from the interesting plot which hooks you in, that's why they can get a little bit annoying. However, they are equally necessary, since they serve to make the world of this anime feel more fleshed out and dense. Thus there existence can be compared to a double-edged sword in my opinion. They are necessary but they can be a bit out of place at times.

B) Complex Episodes- These episodes encompass the main plot, and they are probably the best-written case of a believable storyline in anime, apart from Urusawa's monster I guess. To put it simply, the mystery is laid out extremely well, the plot feels realistic and believable despite having "blockbuster" action elements. And it's extremely thought-provoking while being entertaining. The pacing is proper and there is enough buildup for the grand moments to be impactful, thus altogether the plot is really great. However, the conclusion can be divisive as it fits into a poorly laid out trope.

II). Themes and Philosophy-
Ghost in the shell is one of those few anime, whose plot is centred/based around real-life socio-political issues. As in its completely devoid of any tropes and feels extremely realistic and will be engaging even to a person who doesn't like anime. The anime references a lot of thought experiments and literary works and deals with an array of philosophical, political and sociological themes, which were relevant to the time period it was made in and some are or may be relevant even now or in the future. Some themes and ideas explored are, mind-body conflict, the nature of vigilantism, how easy access to information on the internet affects us, corruption, mind-body conflict, AI Sentience, Is there a line between a man and a machine? and the relationship between corporations and politics. To add up to all this, there is much more, to be found in the Stand Alone episodes themselves. As I said earlier the themes explored are extremely relevant and everyone who is even remotely knowledgeable about socio-political issues will find them interesting. Also, unlike other "intelligent" shows, GITS; SAC's premise is not built around its complex ideas, and the main focus of the series is to put forth an addictive and accessible plot with a lot of dimension to it. The themes are weaved in the show, in a subtle manner as the story doesn't explicitly focus on them thus, they add more depth to the story, making the anime not that difficult to get into.

III). Characters-
I often find reviewers expressing their criticism towards the characters in this anime and it's definitely true. The characters are not developed as well, as I would've expected them to be. However, since it's a highly plot-driven story, there is no real necessity for the characters to be 3-dimensional and they do fulfil their roles really well, so focusing on them heavily is not wise. Overall they are just decent.

IV). Music and Art- The opening and ending songs have their own aesthetic and are extremely catchy. The art was way ahead of its time and the animation is awesome.

V) Conclusion- Highly enjoyable anime, with a plot leaving room for thought. Polished and meticulously done world-building and spectacular animation. This anime is a cyberpunk classic everyone should watch.
My initial score was 90, but the stand-alone episodes were a bit iffy at times, thus the final changed score is 87/100.
