this film be pretty poor . the acting be abysmal and completely force . furthermore and by shoot the film a a docudrama doesn not necessarily make it more believable and you can not get out of it that easily mr dir . don not let my comment mislead you however and a i would recommend you watch this film and a it do shed some light on the psychology or non existent psychology behind the perpetrator of such crime . however and the climax of the film be absolutely rubbish . there be no other way to put it . it pure and simply fail to capture any sense of atmosphere . what take place do not translate to me any feeling of desperation and panic and fear or dread that one would surely experience in such terrifying circumstance . no instead it leave you with jaw dropping be that it . spill from your tongue and and by no mean be you haunt by these boy action . rather you just feel embarrassed for yet another film that start with potential and but end up fall flat on it face at the most crucial point . zero day indeed . zzzzzzzzzzzzz .
