The name of the film "Rain Man" refers to a kind of "self-occlusive disease" patients. Such people are withdrawn, socially uncomfortable, and can only think about themselves, similar to idiots, and there are also people with superior intelligence in a certain area.
The film reflects a general concern in society and gives people useful enlightenment. It turns out that many people thought that such patients could not be cured, but after watching the film, they found that they are still human. If they are given care and warmth, they may be freed from self-enclosed confusion. The vivid stories and specific images of the film play a role that greatly exceeds the propaganda in books and newspapers.
At the same time, the film also reflects family ethics and emotional issues. The reason why Charlie was able to go from being an unreasonable, inherited unrighteous person to finally abandoning evil thoughts and becoming an informed person is mainly because of brotherhood. Although this change is still too fast, the audience enjoys the warm brotherhood from the film that is so lacking in American social life.
As a black comedy, the director on the one hand observes and criticizes the lifestyles of normal people in American society through Raymond’s perspective, on the other hand, he meticulously portrays the changes in the mentality and emotions of the two brothers. The tone of the whole film is sometimes mild, sometimes cold.
Among the many actors in Hollywood, Hoffman is short in stature and unattractive, but he has deep skills in acting. Because Raymond’s character doesn’t have much dialogue, it basically relies on physical movements, such as a skewed head, sluggish eyes, and sometimes even the eyes of both eyes don’t get together. When talking with people, they don’t look at each other but turn their eyes up, etc. The emotional changes in his heart are vividly expressed, so that the image of an "autistic" patient who is "half idiot and half genius" is vividly portrayed. Cruise, who partnered with Hoffman, has a better grasp of Charlie’s complex mentality, vividly portraying his greedy and selfish side, and truly showing Charlie’s brotherhood towards Raymond. The personalities of the characters have not fallen into a simplistic stereotype ().
