On the evening of December 25, Song Joong-ki starring "The Chaebol's Younger Son" ushered in its finale with a national ratings of 26.948%. This is the highest ratings since the series was launched. It also set a new record for the highest ratings of Korean cable TV dramas in history, jumping to second place, second only to " The World of Couples " with a rating of 28.371%.

Under the rebirth setting, Yin Xianyu's body and Chen Daojun, who possesses Yin Xianyu's soul, coexist in the same time and space line. This makes the audience very curious about how the finale will explain this phenomenon. But I never expected that the screenwriter and director only wanted to dig holes, not fill them. After realizing that all the previous foreshadowings could not be returned in a logical closed loop, simply and crudely set up the bloody plot of "Yin Xianyu was not reborn but had a dream" and hastily ended the matter. The second step was the sudden appearance of Miracle Company representative Wu Shixian. After Chen Daojun's death, Wu Shixian avoided Shunyang Group like a snake and a scorpion. But after Yin Xianyu said a few words, he changed his mind and became one of the helpers. The emotional change was too sudden, there wasn't enough reasonable foreshadowing, and it seemed very forced. It is worth mentioning that the finale of "The Youngest Son of the Chaebol Family" also has a reversal-like advantage. That is the emotional line between Chen Daojun and Xu Minhui that has been criticized by the audience before. After successfully preventing Chen Daojun from inheriting the group, the character Yin Xianyu also completed his own growth arc: : he understood his father's hidden love hidden in words, and successfully became the representative of Miracle Investment Company with his own abilities. After choosing the latter between doing things that violate moral conscience and justice for the chaebol, Yin Xianyu finally found the value of life. This ending made the audience feel extremely moved.
Since its launch, "The Youngest Son of the Chaebol Family" has been praised by the audience and the media. From the story of high-energy rebirth and revenge, to the deep ancestral relationship between Chen Daojun and his grandfather Chen Yangzhe, to the fierce and exciting "power struggle" among chaebol families, it is full of highlights and strongly attracts the attention of the audience.
But I didn’t expect that after the plot progressed to the second half (grandfather Chen Yangzhe was offline), plot bugs appeared one after another. The plot laid earlier was not fulfilled, and the finale was seriously unfinished. Three major flaws caused the series to drop from 8.6 points at the beginning to 7.6 points, and it continues to drop. 
1, Rebirth into a dreamy dream
"The Youngest Son of the Chaebol Family" attracts the biggest attraction of the audience. is the high-burning process of Yoon Hyun-woo being reborn as Chen Do-joon, using his new identity to take revenge while taking the chaebol group into his pocket. brings the perspective of God in his previous life, playing with his opponents in applause. Every business battle is exciting and exciting, which makes the audience unable to stop watching. 

This way of handling made the audience feel very dissatisfied. : Because in the original comics, Yin Xianyu completed his revenge after being reborn and successfully became President Shunyang. The whole story looks very exciting. However, the series is completely in the opposite direction. The adaptation is careless and can be regarded as destroying the original work.
and after rebirth turned into a dream, many previous reasonable narrative lines were no longer tenable. If it was just a dream, why did President Chen Yangzhe change history in the past and avoid the plane crash? If it was just a dream, why did Yoon Hyun-woo's love affair with prosecutor Seo Min-joon as Chen Do-joon really exist? This is obviously illogical. 
As the plot develops and the rebirth turns into a dream, all Chen Daojun’s previous plans for revenge and the deep feelings between Chen Daojun and his grandfather Chen Yangzhe have also become fiction. This made the audience who was really nervous about the revenge process for Chen Daojun and cried for the relationship between the grandfather and grandson very angry. It was like watching a "scam" Korean drama, and all the emotions invested were mispaid. It's obvious that the screenwriter and director's handling of the plot is inadequate. 
2. There are too many bugs in the story
Leaving aside the bloody plot development of "rebirth into a dream", will talk about the narrative line of Yin Xianyu waking up from a serious injury and revealing the ugly true face of Shunyang's heir Chen Xingjun. In order to ensure that Chen Xingjun can be brought down, Yin Xianyu teamed up with Xu Minhui and Miracle Company representative Wu Shixian, and successfully revealed the truth about "Chen Xingjun's father killed Chen Daojun many years ago" in front of everyone. 
This plot looks great, but in fact it is full of bugs. The first is the question of how Yin Xianyu successfully evaded the pursuit of the chaebol family. In the first episode of , he was pushed into the sea by a hired murderer, unable to resist. In the last episode, his IQ suddenly exploded and he easily escaped the pursuit and capture of the chaebol. In order to complete the plot of "Yin Xianyu successfully defeated the chaebol family",
Even while Yin Xianyu was still in the process of being arrested, he swaggered in front of Chen Xingjun's henchmen. I just missed typing the words "Golden Finger Wide Open" on the public screen. 

There is also the memory of Yin Xianyu that confuses the audience the most: The finale stated that Yin Xianyu witnessed the death scene of Chen Dojun many years ago, and Yin Xianyu also left behind the "evidence of the phone call" that he witnessed the death scene. But the previous plot showed that before his rebirth, Yin Xianyu did not remember that there was a person named Chen Dojun in the chaebol family.. In order to successfully reveal the truth about Chen Daojun's death,
forcibly created illogical clues and added storylines that had not been laid out before. The ending is satisfying, but the logic is lost, which can be said to be more gain than loss. 
As expected, the finale showed that the reason why Xu Minhuang clung to Shunyang Group was because he wanted to avenge his former lover Chen Daojun. Xu Min's deep and passionate emotions made Chen Daojun's death less tragic. Because there are always people in this world who remember him deeply and are committed to seeking justice for him. 

However, even with these two advantages, they cannot stop the fact that "The Young Son of the Chaebol Family" is unfinished. In the blink of an eye, fantasy turns into fantasy drama, and revenge turns into a dream. Although Yin Xianyu succeeded in revenge in the end, Chen Daojun did not know which time and space he was abandoned in. For a drama that was originally claimed to be a rebirth and revenge drama, the loss of a true depiction of the life of the most important character Chen Daojun is undoubtedly the most fatal flaw and blow.
