"Law & Order: Special Victims Unit" began airing in 1999. It is one of the three sister dramas of "Law & Order", the longest-running crime drama in American television history, which premiered in 1990. The other two are "Law & Order: Criminal Intent" in 2001 and "Law & Order: Trial By Jury" in 2005. Young women who were brutally murdered, babies who were abused, girls who were sexually assaulted by close relatives, women who were at a loss under the shadow of domestic violence, dysfunctional and distorted family relationships, parents who wanted to be attentive but were always unable to do so, and those who were on the edge of social, family and interpersonal relationships, and the gray area of human nature. SVU always touches the soft area that people cannot guard against. Cute children, innocent vulnerable individuals (sexually assaulted, homosexuals, and mentally ill), and parent-child and family relationships that everyone has some experience and feelings about. The plot doesn't have to be complicated -- a single mother who is busy with work shakes her one-year-old daughter to death violently, and the innocent girl is crushed by her mother's momentary rage. On the one hand, we can understand the kind of tug-of-war, the exhaustion of working and parent-child relationships; a child who is like an angel when cute, but like a devil when crying and making people crazy. How to accuse the mother who resolutely decided to stop the ventilator because she didn't want her child to continue to suffer from illness? So even if this is a kind of sentimental acting and manipulation, it always makes the audience's heart clenched... and the army is broken... For a procedural drama, the plot and its design are the key to success. SVU is quite good in this regard, and it also continues the tradition of the Law & Order series. The private lives of the protagonists are almost not touched. The advantage of this is that the audience can watch any episode at any time without worrying about the plot being disconnected. The disadvantage is that the audience group is constantly changing. Easier to attach, easier to detach.L&O:SVU's biggest selling point is sex crime. Thanks to the excellent realistic creative team, the most powerful point of "Law & Order" is "as close to reality as possible". Although the fast-paced TV series cannot completely restore the difficult judicial procedures, the show still strives to be true in details. On the contrary, scenes such as explosions, car chases, chases, fights, and gun battles rarely appear. The two policemen who appear as the protagonists have never fired a shot in the entire 22 episodes. They rely on their two legs and one mouth to investigate the case. I believe that everyone who knows something about the judicial department will agree that this is the real way the legal system works. Many judicial professionals and police officers have praised the show. Those who like it say "this is reality", while those who don't like it criticize it as "like a popular education class, not a TV show." The popularity of the show has profoundly influenced the American television industry. Since then, police and gangster TV series have paid more attention to documentary flavor and team spirit, such as "Crime Scene Investigation" (CSI) and "NYPD Blue". The biggest difference from other police and criminal TV dramas is that "Legal" focuses entirely on the judicial process and hardly touches on the private lives of the protagonists. In a one-hour episode, the police investigate the case and the prosecution tries the case. The advantage of this is that the audience can watch any episode at any time without worrying about the discontinuity of the plot. In sharp contrast to it is "New York Major Case Files", which, while telling the details of real crimes and solving them, also focuses on portraying the ordinary life of the police and adds a variety of romances. The most amazing thing is that many stories in "Legal" are directly from social news in newspapers, so at the end of some episodes, there will be such subtitles: "This episode's story is inspired by a certain case, but the characters and specific plots are purely fictional, and there is no intention to allude to the people involved in the case.
