All right - it's an animated series, but it's a TV show none the less.
I saw this a while ago - it's a long series, spanning something like 80 episodes or more.
It's a mature take on an intergalactic war - no humor here, but the characters and the story are well written. There is a fair amount of political philosophy and intrigue here and it does make you think.
What I found to be particularly interesting was the author's inner conflict in deciding which political system was superior - democracy or theocracy.
