None of this matters. More unforgivable, I was not entertained.
I don't know. I feel like this is an interesting experiment in propulsive voiceover narration. It's too long, I didn't care about any of the relationships, I wanted them all to be killed an hour earlier, and the daughter Amy is not a real character at all. I suppose that this lack of concern for the reality of the child reflects the thematic fact that she doesn't matter to the adult characters after all, but there was a more interesting story to be told from her perspective than from the perspective of the self-destructive adults around her.
