Sidonia no kishi was one of the second best anime's I've see. Second best because there were a few minor things that bugged me. Overall though, it paints a realistic picture of what it could be like to live on a ship in space a millenia from now. It has a budding romance between two young Pilots that ends in a surprising way that keeps you coming back at least for the dark heartbreak. The action secenes were amazing and pretty for CGI. I really don't have enough good things to say about this.
