"A comedy film directed by Lu Sang-hyo and starring Shin Ha-kyun, Lee Kwang-so, Lee Chan, Park Chul-min and Kwon Hae-woo, it tells the story of a man with a first-degree physical disability and a man with a mental disorder." A more standard movie is also a more standard Korean movie. There is nothing particularly important for deep thinking, but the viewing experience is good, very touching, and can also arouse the audience's attention and understanding of people with disabilities. Recommended to watch the movie. There are no hard injuries overall, which is very good.

Pros: Lots of advantages. For example, the performance of the two protagonists, the meticulous performance of the daily life of people with disabilities, etc. What I personally like is that the director handles the atmosphere of the film relatively easily, even with a comedic effect, otherwise the theme and story may be more depressing. This relaxed atmosphere is also well conveyed: disabled or not disabled, life is hard when it is hard, and happy when it is happy. Instead of blindly selling misery, emphasize the difficulties in their lives. Of course, this is a very subjective point of view, and I have no way of knowing whether such a treatment is appropriate in the eyes of people with disabilities who have different experiences, and some people may agree and some people disagree.
The similarity between "My First-Class Brother" and "The Taste of The Sand" that I watched two days ago is that both focus on disease. One focuses on disabilities and the other on infectious diseases. In contrast, "My First Brother" is more meticulous and grounded, allowing the audience to understand the plot and characters relatively easily. The shortcomings of "The Taste of Chengsha" in this regard have been written before and are not mentioned here.
Perhaps the favorite is the setting of the two protagonists redeeming each other. This two-way redemption setting is really no matter how to shoot, as long as it can be filmed well, it is very touching. It's hard to live, and the world isn't a good place. But if you can meet the person who redeems you, it doesn't matter whether the world is beautiful or not, because in each other's hearts we are all special, and the time together is happy. I think everyone needs this strong relationship of trust, regardless of gender age and origin of both parties. It's just that some people have met, and some people may not meet them in their lifetime.
Cons: It is indeed in line with the characteristics of Korean movies in terms of excessive sensationalism. The movie is a true story adaptation, I tried to find the original event, did not find anything, it seems that Park Dong-kyu should be suffering from autism (it seems to be commonly known as autism, not the autism we usually hang on the mouth of "I am autistic"). I've seen some autism-related content. For me, Korean sensationalism makes Lee Kwang-so's performance slightly distorted in individual scenes. On the whole, Lee Kwang-so has a really good grasp of the state of autistic patients in various conditions, especially the anxious state, which is very realistic. Should have done a lot of homework. But I don't know why he seems to be out of the state of autism as soon as there is a crying scene, which makes me think that he is a person with no brain defects. Acting, it is definitely difficult to act, then if this situation is not good, I think we can consider not crying, only express joy, the presentation effect may be even better. Park Dong-joo aside, other actors also have the situation of acting well as a whole but using too much force in individual scenes. Probably it is a Korean specialty, and it cannot be changed.
Part of Park Dong-kyu's mother is handled roughly, but it has little impact on the overall plot. See some 3-star film critics say they don't like this movie because Lee Kwang-so's performance is eyebrow-raising. I don't know what to say, but if I don't understand autism, it is recommended to understand a little bit and then watch the movie.
