"I Am a Witness" is adapted from South Korea's "Blind Witness". Before watching it, I heard from a friend that "Blind Witness" was better filmed, so I suddenly became interested and wanted to compare the Chinese and Chinese films. Han is the difference in this movie. There is a word about preconceptions, so out of selfishness, I wanted to watch the Chinese version first and then the Korean version. Unexpectedly, I really felt a lot after watching the Korean version. In terms of acting skills, the Chinese and Korean actors are all beautiful women with young talents, and their acting skills are very good, which is very eye-catching. The shooting style is also very similar, including shooting from the perspective of a blind person, but the plot has still changed a lot. In terms of the setting of the villain, the Chinese version is a perverted plastic surgeon. His sister used a dating app. He accidentally killed his sister when he was angry. From then on, he began to take revenge on the girls who used the app. He did not take this into account. The girls were killed and transformed into the appearance of his sister. . . . The Korean version is about a perverted obstetrician and gynecologist. He is simply mentally perverted and mentally disabled. He just rapes some girls and then kills them. I feel that the Chinese version is conservative and always gives criminals a reason to commit crimes, while the Korean version is real.

Due to the different setting of the villain, the whole story is different. The Chinese version pays more attention to the word fate, and everything is a coincidence. For example, the male protagonist turns out to be the lead singer of the band who replaces the heroine’s brother. The villain Hatred arises from love, revenge arises from love, and the heroine once harmed her younger brother because of love, so we all have similarities. The Korean version does not pay attention to these coincidences. There are not so many coincidences. It just relies on a compact plot to promote the development of the story. I feel that the design and arrangement of the Korean version are more reasonable. There are not so many coincidences in the world. If there are too many coincidences, it feels like Untrue.

As for the ending, the Chinese version uses the happy ending that we Chinese like. The protagonists all live a good life, and even the police I have been worried about are not sacrificed, while the Korean version It uses a vague ending. The female protagonist and male protagonist are both good, but the life and death of the policeman are not revealed.
