Based on looks

MY reaction to this movie may seem superficial, but I can't get beyond the observation that she is just not very good-looking. I don't mean "movie star" beauty. I mean just ordinary attractiveness. If I saw this girl on the street or at a party I would describe her as mousy, plain, not sexually attractive. Her hair is raggedy, her expression is morose, her body is flabby and unfit.
When he makes her undress in front of the long windows he say "I want to see how beautiful you are." Then he just stares at her and doesn't say a word. He doesn't say "how beautiful you are," or "I love your breasts,'' or "my what a fine bush!" Nothing at all. She is so humiliated that she turns her face to the wall and cries. And still he says nothing except "Come over here."
The whole premise of the movie, so far, has been two young people falling in lust. Falling in love may come later, but it never does, partly because the lust doesn't even work.
