This isn’t exploitation; this is a look at how things may have been with Harris and Klebold, and how something like this could easily happen again.

Consistently riveting. Anything but sensationalistic, pic powerfully illuminates the banality of evil, as realistically ordinary kids (played brilliantly by non-professional high schoolers) prepare to wreak havoc.

Honestly, I really liked the movie. I didn’t expect it to be that good. The actors were great, the story was awesome, and the ending was satisfying. The story was well put together, nothing extra, nothing unnecessary. I’d give it an 8 out of 10.

One of the best movies about school violence I have ever seen. Not only does it show how they plan the whole thing, it makes it very realistic in terms of equipment used. Any person who isn't interested in true crime would be quick to assume that these two are Harris and Klebold.

Without even trying, Coccio may have stumbled over the truest metaphor for Columbine yet.

Washington Post
The movie can't help but resonate with a ripped-from-the-headlines topicality.

The New York Times
What gives the movie its power is that even the most innocuous scenes in the boys' lives are shadowed by dread.

Dallas Observer
There's something about that project that feels manipulative and wrong.

Meant to be purposefully banal. Unfortunately, there's a thin line between purposefully banal and simply banal, and Ben Coccio's debut feature too often crosses it.

Generally speaking, I hate films that are shot on camcorder, but they do make things more realistic. This was a necessity for the film, Zero Day, which gives an in depth look at the psyche of two school shooters. The story isn't unexpected or anything you haven't seen before, but what makes this film unique is how the producers went about casting this film. The entire cast is made up of ordinary kids, with no previous acting experience, to that end, the entire immediate family of the shooters are also used in the film. Given that these kids weren't actors at the time, a lot of scenes also remain unscripted. The kids were told to just talk about things that make being a teenager tough, expressing dark, innermost feelings of rage and hatred of society. It was then that the writers wrote dialogue that corresponded with what these kids were saying. The result of this is one of the most realistic films I've ever seen. It was like actually being able to watch the video diaries of the Columbine shooters, expressing their feelings, and explaining their actions, prior to that tragic day. Both boys featured in the film are terrific and the way the Director just let the story flow, based on what these two kids had to say, was absolutely ingenious. I think this film was an amazing insight into the minds of troubled teenagers and I think it's a must see for anyone in the field of education.

In high school, you're told you can do anything you put your mind to.
