This movie is interesting in the aspect of director's decisions. One of those is a slow narrative and brevity. The dramatic side seems to be unfolded out of the screen, we can only see some aspects of conflicts, stories and characters. Everything that is shown is not completely revealed that turns the whole movie to a blend of hints, sometimes we can only guess the feeling of a character by an emotion or a phrase. The main instrument the director uses to tell the story and acquaint us with characters is detail — everything important is shown through details. For example, a string Phil makes for Peter symbolizes their connection. It is so important for Phil to finish the work as soon as possible, because he understands he's a dead man walking, but he badly wants to save that connection with Peter. That's why Phil became mad when Rose sold the skin he had intended to use for the work.
Let's focus on the episode when Peter finds Phil's secret place full of incriminating stuff, including a magazine full of naked men pictures. Peter seems to find out a secret about Phil's sexual orientation, but they never openly discuss this later. This topic in general may be guessed only by emotions — no direct actions or questions in the whole movie.
Details are also used to show contrast between characters. Let's take Phil and Peter again: Phil is a rough man, who denies personal hygiene — so he works with animals without gloves, while Peter is neat at everything and thus he is shown only in gloves while working. Phil and Peter are connected by the craft — but while Phil's making a tough string out of skin, Peter's into making fragile paper flowers.
