A beautiful anime about a girl who travels to the underground kingdom and how to survive the loss of a loved one.
In this film, Shinkai expresses deep respect for his favorite director, Hayao Miyazaki. And just after this anime, people started talking even more actively about the fact that Miyazaki finally had a worthy rival (or successor?). Here you can find echoes of "Castle in the Sky", "My Neighbor Totoro," and "Spirited Away".
