zero day be base of columbine high school massacre . and it a video diary of two boy . at first you do not know whats go to happen you think it be just a bad student film . until they start talk about the horrible thing they be go to do in this quite school . until they start talk about pipe bomb and gun and go shoot in the wood . they be a lot to say about this movie . all know this film be well a film you forget you watch a film and watch a real video two boy make . the two boy act like they be in a weird cult . they burn all there stuff . like play station game book dvds homework stuff school stuff . these two boy can be anybody your friend you brother or the people you see walk down the street . it go through there daily active ( and that be make a gun . in the video they make it mention the bullying that happen to them and how people say stuff about there clothes and the thing you be into i be not say it right but many people do do thing like that . and also the thing be with this people be suspect to like it because of the sensitive topic they have choose on this film . so thats my review on zero day . and let just say the end shoot scene be mess up .
