Even though the aesthetics of film-making in Sexo con Amor remain vaguely familiar and borrowed -- there's the nice, clean 3-point lighting set ups for each of the scenes with a focus that's just a little soft to give the romantic feel of Barry Lyndon, shot-reverse-shot is a dominant structure of the scenes, the melodrama (although invented in cinema by D.W. Griffith, it's not really a style of Hollywood anymore, it's becoming a Spanish expressionism almost, with soap operas and Almodovar inevitably influencing rising directors more than anything else), and the adherence to story -- the cultural references are undoubtedly different and original than are those seen in the leading American films.
For one, the always-taboo subject of nudity is handled very crudely (but honestly), with almost every other scene including people getting into in-depth discussions while naked or half-naked. It defies the exploitive nature of American film nudity not only because of its overwhelming amount, but the way in which it's used. At one point Luisa's (Sigrid Alegría) breast falls out of her lingerie, as it probably would in real life, while she turns in bed, and not only has it survived the cut, but was probably intentional during the making.
In another scene where uncle and niece get it on together, incest is made seen as if it's almost unnatural to live without. Though to say more about that relationship, it's probably only used in reference to sex (and niece was probably put in there to be a plot device, the sole possibility for the lone man to get access to a woman). A moral compass for that particular relationship is not shown at all. In fact, it's mostly about an older man who copes with cheating on his wife, while there is no hint he's hesitant at doing it with someone like his niece.
Although I wrote above that it adheres to a strict storyline, the conclusion of the plot is not like in the American movies as well, it's open and suggests lack of character growth rather than concluding with a specific point of original intention. And it works, a good question is better than a good answer in this case. Sexo con Amor is a different type of animal, a film rich in Chilean culture and must be viewed without bias from Hollywood-like structures.
