The film "Best Suspect" is unfolded in a multi-clue narrative way, concentrating on polishing the script and paying attention to creating an atmosphere. At the same time, it is easy and funny, and it is also full of suspense. As a major clue of the plot, the elements of commercial warfare will be fully interpreted. The ingenious plot of IQ tug-of-war between characters and the delicate depiction of psychological games not only test the IQ and EQ of the audience, but also narrow the distance with real life.

Secondly, the film brings together a group of little people, such as insomnia, peeping tom, blackmailers, thieves, ghosts, depression patients and so on. In the film, they compete with others and their own destiny for money, love and other desires, making the whole film like an IQ tug-of-war. In reality, there may not be a seamless scam like that in The Best Suspect, but the intrigue between people in business, the greedy instinct of human nature and the portrayal in the film are all wonderful and true.
