The Story (10/10) is ridiculously sick. Just so interesting and well developed.
The Art (9/10) and Sound (9/10) just amplify the whole feel of the movie and the music is so good and comes in at all the most perfect times...plus all the songs are by RADWIMPS, so you really can't go wrong there.
The Characters (7/10) are slightly underdeveloped but I think is probably necessary to keep the story flowing at a good pace.
I think this movie would be extremely enjoyable (10/10) for all viewers, no matter if you're new to anime or have been watching anime for years. I've only watched it once so far and it was really really enjoyable watching it for the first time, but I'm not too sure about its rewatch value because of the nature of the story...but who knows might still be quite high since the movie is such a good watch.
