Binary opposition is the two-term conflict. We usually would see the good side and the bad side in almost every film or the different attitudes toward one thing. That creates the story. This kind of technique is help the audience quickly understand the outline. Even he/she doesn’t finish the film, but he/she will know that the director want s to say a story about the structure like “Yes, I know it is a story about car accident” Also, the audience would know which side they should believe, their emotion could be properly located. It would be easy for them to recognize the character and the ideology. In “Shane,” the two opposite is pretty clear that Shane and the homesteaders are the good side and the cowboys are bad side. Ryker wants to own the whole land and threats the residents to give way. In the first half of the film, we see Shane comes across the land and arrives at John’s home, and we know that he is a cowboy and intends to stay. And the next shot, we see Ryker and his boys also come to this place, tell him the land problem and they have quarrel. Shane returns to the house and help him to fight back the swashbuckler. And we know instantly that we have to support the family and Shane. Ryker is the evil side. The second one is the structuralism. It emphasizes the sameness in films, and “see how they fit onto or help to define a genre, style, or movement” instead of caring about the difference in every film. There are some examples. The first one is to establish the conflicts. The binary opposition is often used. Or the disruption of equilibrium is also common one. There is a pattern. When the opposing force disrupts the plenitude, the seesaw progress occurs between unifying force and the disrupting force. And in the end, there would be a new kind of plenitude. But the new one is not necessary same with the original one. Sometimes this kind of result would generate more emotion and male the audience more impressive. “Shane” is the example. We see the Starretts is a happy family-The strong and brave husband, the gentle and pretty wife and the outgoing little John. And they own a peaceful life. That is the state of equilibrium. And Ryker is the disruptive force. Though Shane’s help, they cast out the evil power. But we see the end is the little John looking Shane leaving. Why? The guns here stand for the badness and that are the original power of the cowboys. So when Shane teaches the little John how to shoot, Emile was angry. I think she is the symbol of the land, which is tended to be peaceful, steady, gentle and not quarrelsome. But the way Shane solves the problem in the end is to with the gun. He knows that he has to use the bloody method because the “enemy” is s killer. That is why he prevents Joey to go to town. Not only he knows Joey could not win Johnson but also he wants him to belong to the “nature of land.” But the price is that he has to leave cause the guy with guy could not belong to the land. Though the situation comes to the equilibrium, Shane has to go. That is the difference. It is a misery because we know Shane has tried hardy to change himself, but it is all in vain. Little John’s innocence and the “sorry” floats in the air, just to enhance the sadness. The third one is codes and convention. At the beginning, we must understand that what the film involves is not only the text (the story) but also the social context. “The social influence establishes the sets of codes and conventions which make communication between the audience and the film possible. Convention is consistent of numbers of codes. And the codes in the film probably are the gestures, the accents and the styles. These hints in the film combine together and become the convention. In some early films, women are shaped like a supportive role, not the main character. In “Searcher,” the females are weak and need men’s help, to be rescued. In “Shane,” the wife Emile is framed in the window, and in the house. The reason might be the conventional value toward women which women are weak and inferior. In “Casablanca,” the special light for Lisa is one example of convention. The soft light and the close up make her face more beautiful and attractive. The last one is the genre. It includes the conception and the codes; rather, it is the system of codes. Genre helps the audience to understand the film and recognize the context. We often mentions about the western films, and action films, the romance films, and so on. It means when we watch the western films, for instance, we would expect the cowboys, the gunfights, or the Indians. In “Shane,” why don’t they call the police when there are quarrels? Because the police station is too far that slow help is no help. We accept this for that this is the western film, and the land is too large. Romance films, we expect to see the lover kissing. The expectation is from the genre, and it is not satisfied, the audience would NOT feel pleased, just like kids always like the happy ending in the fairy tales. After seeing “Casablanca,” I feel there seems to be missing something. Of course I know it is a good film and the story also great. But there must to be something wrong. I realize that though Rick’s love is great and touching my heart, there are seldom shots about the lover. Even though they have ever in the bar or in Rick’s room, most time I see is that they talk rationally or argue. There is little intimacy between them. I know it is a love story, but it seems not to match my expectation. I was typically controlled by the genre. However, I think that is reasonable because the background is under war, and if there is magic love, it would somehow realistic. And the war makes the society anxious, and use the way to express the love perhaps is better than what I think, as a secular audience.
