Beautifully shot, good acting, solid plot, memorable OST, basically your 10/10 right here!!! 1st season a bit low budget as far as special effects go but that didn't affect my enjoyment. Shame it never got a third season, only a low-quality US remake (don't watch).
And to those who 1stared it because of the portrayal of ultraviolence and very unethical behavior, this show is for adults, it is fiction, and it makes one reflect on what crosses the line for "the greater good". You're _supposed_ to feel disgusted at torturers pulling people's eyeballs out and assassins executing kids like it's nothing. Perhaps stick with the Care Bears if you just can't handle it.
