Why would Steve leave a corpse in his back yard? It’s one thing to kill someone; another to leave it out in the open like some trophy. It takes a while to figure out exactly what this movie is about. It doesn’t have a big hook. It doesn’t have a gimmick. The cast is limited to a few people and the story doesn’t need more than that. Just don’t expect a whodunit. Steve either killed or he didn’t.
The film is driven by emotions, flashbacks and dialogue. There are surprises along the way, and they come late in the plot, but they will remain unspoiled. Basically, what you have is a handful of characters trying to explain the murder. It’s a procedural. It’s slow. It’s well-shot and edited gracefully. The photography is often unsaturated and I’m not exactly sure what the color code means.
The script goes back and forth in time and that, too, can be confusing. It is, at the image of his main character, quite depressing. Diane is a drama, a mystery, a thriller and, at its darkest, a horror movie. It’s not particularly frightening, but it has something to say about PTSD. I’m not sure who this movie is for. It’s a cool looking, compact and chaotic story.
