I just really can't put into words how much I love this show. So many things struck a chord with me (some literally
), and many points touched me on a much deeper level than other series I've watched. In fact, the only things I can remember affecting me on this level are Eva and Saikano.
And that's what separates a 9 from a 10. A 9 is: 'Wow, this show is so amazing! I have to make all my friends watch it now!' while a 10 would be: 'This show will change your life.'
And, of course, it's a technically great show, too, with all the wonderful animation, voice acting, music, story, characters, etc.
