Post-Dalinian patriarchal nuclear family critique.
A best case, worst case scenario for the schitzofrentic lightbulb family. The target squids are the neutral resting place for consideration, which is important as contrast.
The woman, voiceless, goes through menstruation, being claimed as property, the sexual penetration of the lightbulb, and finally childbirth of the eating artist. The outside world, characterized by the cat, tv and the sailors of death are but victims.
The factory, that is, the + window seems to be foreshadowing of the proletariat's own self-destruction, the Christian graveyard his fate and the evential breakdown of the self, his redemption. The wings on the man at the end seemed Hitleresque.
