( the description of the mood of the movie may be consider a a spoiler because there be not much action in fact ) great one . be it for my peculiar interest for the dystopia and utopias . be it for the atmosphere of the movie . or be there some more magic . if yes and it be for sure the utmost human one . this film be and no doubt and extremely artistic or artificial ( depend on taste ) . i can imagine most of the people who hate to watch slow movie ( and those of tsai ming liang ( who i do not enjoy other time ) be one of the slow that i know ) and suffer during the movie . yes and people be unable to slow down and to let time pas and to watch it without feel they waste it . one can take this piece a torture or a a therapy . the topic at the surface . the lack of communication even if we live in rabbit cage one next to each other but not really together . people be tire and sick of something and unable to describe it just do not want to meet and touch and talk and confront the others . like if they have disappear . the big block of flat look void and the rain fall constantly evoke the strange melancholy inside . and sometimes it must be something abnormal and unexpected and some unwanted decay a a hole in the floor of concrete that allow u to reach each other . one of the possible way to look at it be this represent don not survey the inner world of the character consider the whole movie space to be inside of yourself . and ask why be it there . where could these depressive state and mood come form . be there a place for them and they do not have a right to be here . and search for the answer ( if you need them ) among the wall and hall of the block instead of inside hardly transparent mind of a man . the key to understand be not to understand to let a movie borrow u a a subject of study inside itself and at the end safely return u to our more colorful and normal look reality . then and maybe and you will reach like me the feeling of real and possible and non pathetic hope and that in core we be still human . and this state of mind can help one much to live in this world .
