The songs used  are meaningful but sometimes they  last for a few minutes that viewers become fidgety in their seats.  Cinematography and shots used are great though,  noticed close up shots all too often of Kotoko's face. Director Tsukamoto depicts ideas that are commonly observed in his films, and in this case the fragility of a person as well as alienation. Kotoko, in a sense is disconnected from the normal flow of society, all in a world of her own. Cocco is a great singer, no doubt about it, but in the realms of acting I think she has to grow more in order to get that connection with the viewers.
