Elephant (2003)
It's good but a bummer. Don't think Ive seen it since it came out which weirdly we may have actually watched at school. It's tense, pretty well acted for amatures, nice little time capsule of early 00s, well shot and paced.
Random thought: why the fuck is there a shower scene in this movie. It's for like ten seconds but there was no need to have a nude woman for one shot
