This show really cared about characters that I've never heard about before, and made me want to read a comic I've never heard of. That's how much I enjoyed this show.
There's so much to like in this first season. Great, brutal action (since the animation shines with it), great and complex characters, great world-building and nice heart to it all.
Now there were things that bugged me, like some characters felt one note and inconsistent (Amber and William) And the animation can be pretty clunky at times, especially during episode 4.
However overall, I loved this first season, but I hope the animation improves for season 2! (8.9/10)
