Well, it's kinda like Star Wars, except that there's no fantasy, such as the force. There's a political struggle between the Empire and the Republic, and you can get to see the pros and cons of both of these views (while there's also an independent faction which favours the side they like the most, and also some religious fundamentalists in the middle). Because of it, it's really hard when it comes to pick a side, as you can get to understand the motivations of the characters who are fighting for their own ideals. The soundtrack is also awesome, I mean, I've seen many animes before, but this one was definitely a jewel ~
