zero day have a purpose and this be not simply entertainment and it deliver a message about it specialised subject school shooting . chart the life of two friend andre and cal lead up to an attack on their high school . whilst the movie start in somewhat unassuming fashion and an impromptu announcement of the come attack in amateurish teenage style follow by some brief encounter with the boys family . it be not long before we be down to business with the boy show u their collection of gun and their fetishistic love of them and their sprawling sporadic narcissistic fantasy and even in a controversial scene how to build pipe bomb . so what be the movie try to say . what be really motivate these soon to be killer . it seem hard to really pinpoint . they certainly do not come across a cold blood psychopath yet they be plan an act of sheer brutality . this bring me to what i feel be the genius in part of zero day . cal and andre talk constantly about how much they be on a different level and how above the rest of u they be and how they will leave u all behind . like the columbine killer they truly feel superior . like nietzsche re sentiment cal and andre value system seem to have be bear out of rejection from their society . yet we be give only glimpse of this and an expression of hatred for a popular athlete for example . so where be the motivation . what i feel be that coccio portray two individual desperate to make a statement of superiority a gesture of their power yet who have no reasonable venue for it . hence they turn to mass murder and the kind of which that will garner them more attention than they could ever realise . this be why in part school shooter seem able to carry out atrocious act despite come from good stable love home . the murder be part of a fantasy and cal and andre be totally lose in their fantasy they almost fail to see the reality of their action . they turn fantasy into tragedy . what be secondly most enthral about this film be the character development and the unique dependence cal and andre have on each other . andre be throughout the film overtly the leader of the two and cal embrace of his demeanour and attire seem somewhat force . andre be uptight and andre be intense and serious . he completely shun others except for his family and he be meticulous and precise about everything he do and for a while appear the prime mover in the plot to attack the school . yet he be likable in his own way and he do not embrace teenage nonsense and in part we feel compel to agree with him and yet these moment be shatter by andre fleeting gesture of violence towards u the audience treat u a both confidante and potential victim . cal on the other hand seem more relaxed than andre and more accepting of reality . yet he be in his own way dominant . we have many personal moment of introspection with cal video diary and scene when he be alone and apart from andre . cal seem to be struggle with his own personal demon and use their plan to exorcise himself of them . andre be jealous of cal go to the prom with an old friend and he want cal all to himself . cal placates andre and encourage him . for the first time in his life andre seem to have find someone who believe in him and who admire him he can not lose it . whilst cal have find someone offer him a way out . the movie certainly pick up pace and improve a it near it grim conclusion . there be an excellent moment when cal attend the high school prom . suddenly the star of the movie become shy and introverted and not at all at ease with his peer . yet we be incline to feel more connection with cal than with the raucous bawdy crowd scream juvenile obscenity whilst drink heavily in their limo . theirs be an episode all too common and recognisable . we do not want to relate to them and when it be over and cal be back with andre silently prepare one of their final video we like the character feel once again at ease safe in the fantasy world they create . we feel like shun the mass a they have . the penultimate scene be superb . the final video see andre and cal arm themselves in their car just moment before attack . it be all too real and truly create a sense of impend doom . by know we know cal and andre and be realise they be about to actually do it and with a kind of morbid fascination we be also relish the films catharsis . the massacre shot in cctv fashion be at time shock and and whilst it be certainly the perfect choice to depict the massacre if we be go to it be not void of flaw . what be most significant be the sudden radical change of perception we have of cal and andre and look at them in the this person suddenly they be the callous killer we know they would become yet refuse to acknowledge that they would . it be violent and real and our hero have become monster and the reality of their fantasy be a terrible tragedy and which cost them everything . the final scene show a group of teen film themselves burn the cross erect for andre and cal in disgust that they have be memorialise . have know andre and cal we can only feel almost a sadness that they be actually go forever and that they certainly do not win anything . zero day be a must see for anyone interested in these violent act sensationalised by the medium . it be a character study well worth experience .
