Legend of Galactic Heroes is an OVA that ran from 1988 to 1997, with a total of 110 episodes.
The series is set ~1500 years into the future, although in terms of technology, it's basically the present but with spaceships and flashy guns. This is most likely horribly inaccurate, but I believe it's intentional, because the series deals with many themes that are relevant in our present reality and these themes would lose their impact if the show was set in an unrecognisable future.
In this distant future, humanity has colonised hundreds of star systems and divided into two factions: The Galactic Empire and the Free Planets Alliance. These two factions have since been at war for centuries and the OVA centres on two catalytic characters on opposing sides: Reinhard von Lohengramm of the Galactic Empire and Yang Wenli of the Free Planets Alliance, but there are many more characters of importance; the series is notorious for having an extremely large cast, as pictured on top of TVtropes article for the
Loads And Loads Of Characters trope.
This animé is
awesome. I'm a little less than 1/3d through, but if it keeps this level of quality up the whole way through, it'll be one of my favourite animé of all time, along with Death Note and Code Geass. They are kind of similar in some ways, too. Much like in those two series, the main conflict is not between a hero and a villain but a hero and a hero.
I have given it a 9/10 on myanimelist, for now. The main reason why I haven't given it a 10/10 is because the art isn't very good. And it's not that I mind that it's old. There are a lot of repeated animations and scenes that are just unnaturally still as if the animators couldn't be bothered to put motion in them. And even when the art isn't plain bad, it's just not very remarkable.
Plot-wise, it's a 10/10 though. It's just my kind of plot - it's intricate and detailed as hell, thought-provoking, full of allusions to historical events, and it echoes the sentiments of ancient philosophers beautifully. Moreover, the classical soundtrack is very tasteful and fitting. I wouldn't call it one of my favourite soundtracks but I just can't complain about it because it
fits.
If there was any more I had to say about it, I forgot it. Highly recommended animé.
