a a mental health researcher and i be always intrigue by movie that display pathology . so when people start do thing that be not explain by an underlying mental disorder and i get confuse . perhaps because of the translation ( or a poorly write story ) and i just do not see what her underlying reason be for her self mutilation . i think maybe it be something akin to body dysmorphic disorder ( evidence by see her disconnected hand on the table at the business dinner ) . i couldn not quite understand what be go on with her and and i would have like to see some reasoning for her pathology . unfortunately and lack any sort of character drive force and this movie seem like an excuse to shock the audience with something on the edge of disturb and taboo . because of the lack of character development and it seem simply to be an exercise in exhibitionism and which certainly dampen the effect of the film .
