First source for the research paper

The topic I choose to discuss is different characteristics and features of melodramas in Korea. Also I am going to specify one or two directors and mainly talk about their works. First source I am going to use is a movie called "I saw the devil" by Kim Jee Woon. This movie is really interesting because it contains many different features including those of melodrama. To briefly summarize this film, "I saw the devil" is about a husband chasing after a murderer who killed his wife. However, the interesting thing about this movie is that this husband is more of a psychopath that the murderer so the husband intentionally let the murderer escape just so he could recapture him and make him suffer again. However, the murderer eventually finds rest of this husband's family and does not go through as the husband planned. This source is useful because I am going to compare this film with some other films of the same director. I am also look for some melodramatic features of his films so evaluating "I saw the devil" is definitely an important process. This source is reliable because this film is one of the best representation of his works and I guess this is an subjective source because it is a work of art. This source will definitely fit well into my thesis paper because it would reflect the director really well and really show his style of presenting his thoughts into a film.
