A must-watch anime indeed. If you've ever dreamed of being able to delete people with your mind this anime basically explores this idea from the hero's perspective. The anime has far too many messages that yell in your face to all subtle and too many scenes of people crying to be emotional. The massacres and fight scenes are pretty well done and the CGI doesn't stand out too much If it wasn't for the last episode this anime would have rated a 9 at best, but because the final episode was alluded to so early on you already knew the ending by episode 6.
