If you're looking for the human rights theme... you might be disappointed, tbvh. They basically have nice nice speach here and there but the theme is lost in their actions.
But, you're looking for an action lakorn than this is amazing! Well, at least the first part, personally I think it would've been an amazing 10-12 eps, after it basically dragged, but it was still watchable.
But ahhh, the initial fights... I loved so much! The best I've seen so far!
I also LOVE the ost, the main song kind~a became my fight song, one that you listen to and get powered up to go and do whatever you need!
The romance wasn't big deal, maybe it wasn't really necessary, but worked for me to not get tired of so much bad things, fighting and killing, so it wasn't bad.
Overall, worth checking.
