in my honest opinion and everyone should see this movie at least once . it really put thing in perspective a i watch it . though it be fictional and this movie be about something that could happen to your child . it show how easily two kid can hide both their hatred for their school and and their plan to murder innocent student . this film would not have work in any other format . they pull off the hand hold camera and perfectly . it remind u of april 20th and 1999 and when eric harris and and dylan klebold murdered 12 student and then themselves . it also remind u of the medium storm that follow after . everyone want to see the rampart video and everyone want to see the basement tape . this movie be a fictional version of our dream come true . we get to see the kid behind the monster . the only bad thing about this movie and be that it do not do well on the market and and few people even know it exist . if it would have have a single preview on a single blockbuster movie and everyone would have go to see what the big deal be about and zero day . i believe this be the best film adaptation of a school shooting of the few that have truly attempt it . the shoot itself only take up about ten minute of the hour and a half long film and because it mostly focus on cal and andre and and what they do up to that point . if you have not yet see this movie and go rent it and and watch it . i guarantee that when it be finish and you will be speechless .
