1. At the beginning of the film, including the previous part of the plot, the murderer's face has been deliberately not photographed, even if the black police and his companions searched for the murderer's residence (or "laboratory") At the time, the murderer was always wearing a cloak. It's not until the Doctor decides to do a scene with Adam that the film actually switches to Sepp in front of the surveillance screen. During this period, the "murderer" seemed to tell the audience without warning. I can only say that this made me suspicious. Why was the identity of the murderer hidden all the time, but it was suddenly revealed? And in the end, when Saip fought with the doctor's family, he didn't put on a cloak to fight. It may be a bit ridiculous, but when I watched the film, it really aroused my suspicion, because the film has always portrayed the murderer as a mysterious person behind the scenes. The characters, from the masked villain to the cape, can be seen, while Saipu wears ordinary clothes to fight with the doctor's family, which instantly weakens the murderer's ruthless role, not to mention that during the fight, Saipu wears ordinary clothes. Layer once succumbed to the doctor's family, which is too inconsistent with the murderer's high IQ personality.
2. When the doctor turned off the light and told Adam that he was going to act, Saipu, who was in front of the monitoring screen, was very impatient with the sudden black screen. This means that this set of monitoring equipment was not made by him. He was very unfamiliar with it, and he was not. The real murderer. If it is the real murderer, the environment at the beginning of the film is in a dark state, and it is impossible not to know that the screen will be black when the lights are turned off.
3. The real murderer deliberately used electric shocks on Adam in order to expose their acting, that is, Adam faked his death. Just imagine, in the film, Saipu obviously doesn't know what happened when the screen goes black, so he can't know what's going on inside, and then, no one outside except Saipu can see what's going on inside , so the real murderer is likely to be indoors.
4. At the end of the film, the black police chased Saipu into the real murderer's laboratory. Saipu was forced to the end during the escape process. This shows that he is not very familiar with the building structure in the laboratory, which means that the laboratory is not his. Moreover, when the black policeman and his companions came to the laboratory for the first time, the real murderer escaped by cleverly using the pre-set mechanism in the laboratory, and when Saip escaped into the laboratory, he not only He didn't use the mechanism, and he was forced to the end. Saipu's unfamiliarity with the laboratory environment showed that the laboratory was not his, and the real murderer was not his.
I have only watched this movie once. The review is based on my memory. If I remember some details wrong, please forgive me~
