spoiler alert . this movie and zero day and give an inside to the life of two student and andre and calvin and who feel resentment and hatred for anyone and anything associate with there school . they go on a series of self think out mission all lead up to the huge mission and which be zero day . zero day content be not specify until the middle to the end of the movie . the viewer know it serious and fill with hate but be never quite sure until the end . now we all know and if the movie be base on the columbine massacre and the end be pretty obvious . and the end be no different than any other movie about the attack and they go and kill many of their fellow student in the end . i have see a lot of movie on this attack and and this movie by far be my favorite and and most respect . it give the viewer and inside look to the life of these two teen who hate life and and honestly it give the viewer some what of an understanding and and a closure on the horrible event . be only 7 when the event play out and i never know the seriousness of the shooting and until my english class be assign an essay or story on a defining moment in our generation . well i know everyone be go to pick the twin tower and but i want to be different and because of course the twin tower be tragic and very defining and but i didn not think it be the right choice for me because there be really no way of relate to that because and i be only in the 3rd grade and i have no idea what it all meant . but the shooting do leave and effect . i remember the interview and the sky view of the school and and the hurt and terror in the eye of thousand of people . this movie be a compelling and down to earth and and horrific masterpiece and and i would reccomened it to anyone .
