It offers rich commentary on war, politics, government, history, corruption, good and evil, etc.; the list goes on and on.
It would take too long to explain the social commentary going on in this series, but one thing that stands above the rest is how tyrants come to power. Is it through the people (democratic rule of the many over the few), or government control (aristocratic rule of the few over the many)? Does the goal of a perfect system begin as a good dream that becomes tainted, or is the dream already tainted? How long does it take a system to grow corrupt? Is the system at fault or are the people who run it? It asks a lot of these questions by setting up a corrupt (or rather decadent) democracy that is fighting a growing benevolent aristocracy that has just overthrown a tyrannical government. Of course, it addresses the problems of a single monarch's rule versus representative democracy; there are good things and bad things attached to each system.
The show creates political and moral problems and the characters on both sides must find solutions. The story itself remains very nuanced to allow the audience to make up their minds about the issues presented. There are advantages and disadvantages to all forms of government presented. That is, the story is not a one-sided narrative that forces its audience to choose a certain side. It is a complex and intelligent social commentary, which forces its audience to think about all kinds of things. I also really like how classical music forms the soundtrack; that is, classical pieces are the only music in the show-Bach, Beethoven, Handel, Mozart, Brahms, Schubert, Wagner, etc.
It is a masterpiece, but it can be very slow at times. It is basically the War and Peace of anime.
