Something significant I appreciated about this film was how we could see into what the individuals were thinking and feeling through their actions. The actions themselves can often seem misguided or off target until you, the viewer, consider what led to the particular outbreak while trusting the filmmakers knew precisely what they were doing.
For example, the wife would lash out at the husband for falling short in various ways, all the while we see him being a caring husband and father. In a way, her being able to express herself to him in this manner showed evidence of a safely zone between them; this is, that she could do this demonstrated she could be confident he would have some sense of where it was coming from, and that she would know that he knew. How familiar to those of us who have experienced such relationship characteristics, in ourselves and in others! One success of this film is its ability to tap artfully into the familiar like this.
