Much closer the the Italian Neo-Realism in its mood and subject matter, rather than to the canon of black series, A Day Without The Sun tell the story about a lonely and a bit sad man, lost in urban realit. It brings to mind Umberto D, a film by Vittorio de Sica. Because of the staged scenes it is not a "pure" documentary....
The story also happened to the lead actor in real life, feel sad that human nature still has not changed. All casts are good, in particular the male lead's acting is excellent! Movie is well made, each main character has their own song, music style reflects chinese music's elegance, strongly recommend!
