I believe that the movie represents a narcissistic, controlling, and perfectionistic father. and his impact on an impressionable teenage girl and a wife whom, through his manipulations. he has kept a prisoner. In the beginning, every scene begins with the perfect family, eating the perfect meal together with one hitch, his constant disapproval of everyone but himself. It is no coincidence that Airam is Maria spelled backward, since Maria's "twin" is her mirror image, real or imagined. The only thing the father is interested in is perfection, hence, his chosen profession. He corrects flaws in beauty, and is more concerned with the external image his family has in the world, than whether they are floundering and dying internally. His answer for his daughter's pallor? Not enough sleep or put on makeup, after all, the whole world will be looking at and judging you by the way he judges everyone, on the surface. Does he see his daughter as "beautiful"? No because there are his concept of "flaws" with her ears and her nose. There might have been twin babies and one was chosen not to survive because she lacked perfection, she was "deformed" so there was no sense saving her. The father keeps the mother sedated because he wants to erase the fact that she (not he because he lacks any semblance of empathy) lost a child who should have lived, could have lived, and as any mother, whatever deformity the child had, would not have prevented her from loving her daughter. "Look Away" is an apt title for a narcissist who cannot look at any imperfection in his family, because they are a reflection of him, and all things reflecting on him must be perfect. Whether Maria had dissociative personality disorder or not, whether there was a cosmic switch in the two young women or not, I do not feel is the point personally. The point is that the narcissist will do anything to manipulate others into doubting and loathing themselves. That is their strength, through manipulation and control. They have no empathy and the only important thing is how they see things and how others might see them.. He has his wife doubting the memory of her own delivery, and is making his daughter's fears and depression worse by constantly bringing up her flaws. Maria/Airam had to kill him. There was no other way to escape his narcissistic grip, no matter what the cost. The narcissistic father had perfect foils for his own personality disorder; two empathetic, weak and vulnerable women, until one emerges with enough strength to become killer.
