Lack of cohesion and rhythm changes of screenwriters. It is difficult for a police drama to get out of the cliche of "solving a case+love". This is the viewer's constant appreciation habit. No matter how to break through the police drama, we must design all kinds of suspense, and the plot must be ups and downs, interlocking, so that people can't bear to tune in and share joys and sorrows with the characters in the drama. I will cry with Yan Ming, because Lei Lei had an accident in a black hole. I will dare not fight because of Tong Andong's repeated injuries in the dangerous process; I will rejoice at the growth of four police flowers in the sonorous rose, and I will also regret the reunion of Lao Luo and He Xiangyun. Every drama should have a focus and a lot of emotions. Strangely, "Public Security Director 3" is such a gangster drama with no suspense. Abin is the undercover of the underworld in the police. He should be in suspense, but as soon as he appeared, he was marked as a bad guy and was quickly seen through by a clever audience. I was angry for the police comrades when they were looking for thieves everywhere. It's no secret that the police went undercover in the first episode of the underworld (I can't remember his name, because the screenwriter ignored him, and no one mentioned this unsung hero when the living received the certificate. ) The biggest suspense of screenwriter design should be the victory of old Hu Man. The directors have good intentions towards the old man and tried many ways to hide it for him. For example, sound processing, such as multiple appearances without giving positive shots, etc. ; The police tried their best to find the old man. But the audience watched it easily, because in the tenth episode, when the police successfully seized a large number of drugs on the Sino-Vietnamese border, Hu Shengli did not have the joy of success, but looked at his watch with a hint of sneer. "It was just three o'clock, and we won." Alas, there is no danger of exposure. The final facts also prove that Hu Shengli did not deviate from everyone's guess. There is no suspense in the drama, which makes people see that nature lacks eye-catching and thrilling aspects. In addition to making people sleepy, it seems that there is not much aftertaste left.
