i be frankly surprised how little have be do in film on the columbine massacre . there isn not a major documentary and very puzzle . fortunately we be grace with the talent of ben coccio who direct zero day and and gus van sant who do the equally fine elephant . two different take on the event and which have in common the idea that the real cause of the massacre will always be a mystery and that there something ultimately baffling and unknowable about the motivation of the two killer and and what actually drive them to carry it beyond fantasy into horrible reality . zero day and purportedly make up of videotape make by the shooter and find after the event and be absolutely rivet . even if you know where it go and you still harbor hope that it wont go there . and the tension in the final minute of the movie be excruciate . the film be terrific from top to bottom and from director to script ( not much improvise and though it appear very spontaneous ) to the two lead actor and and the support player as well . there be only one aspect of zero day that trouble me . okay and so we can not fathom why the shooter would do what they do and but certainly one of the contributor be their anger . yet these boy do not really seem angry . they may say some thing to indicate that they be and but in fact they do not convince me that they have something inside them that compel them to kill innocent people . but this still leave me with the sense of why . that director coccio want me to have . anyway and rent or buy this movie and it will creep up on you and stay with you for a long time . the blair witch folk could only wish for the kind of success these guy have at make a mock documentary .
