Query: Eerie and haunting nightmare

This film gives no explanation, no backstory, and no judgment as it presents a Columbine-esque tragedy at a high school: two boys plan to shoot as many people as they can on a regular afternoon when everyone is going about their business and nobody sees it coming. Here's an example of tracking shots that actually work in their extended form. You focus entirely on one person as that person goes through the mundane high school life: cafeteria, classroom, library, photo development, gossip, and the emotionless planning of the massacre too. Also an intriguing example of multiple versions of the same scenes as the focus shifts from one character to another.
