There's not a lot to really say about Shinano Mainichi Shinbun. It i just a 15 second clip of a girl running after a train. Story: 1/10 There is no story. No context. No nothing as to what is going on. It is just an unnamed girl running after her dad on a train. Art: 10/10 Shinkai's works are always so beautifully illustrated and animated, no matter how small they are. As usual it has surpassed expectations. Sound: 8/10 The music was really pretty, despite it not being very long.Character: 1/10
There is no development with the characters, since you only see them for 15 seconds. There is nothing to go on with that.

Enjoyment: 5/10
Despite it being so short, I actually thoroughly enjoyed watching it. Shinkai has a strange charm to his works that make even the smallest work memorable and precious.

Overall: 4/10
It is only 15 seconds long, if you can't spare that time then you need help. It is pretty and nice to watch, even if you do not know what is really going on, or what the story is.
