I feel that this drama is stylized in Netflix. Really suspect that the script structure is out of the big data box: sci-fi, suspense, gun battles, movements, fantasy, all kinds of elements that can not be combined, mixed in a strange style, nothing and nothing to play. The story starts rather good and yet ends poorly - the fascinating opening, the unsuccessful development, the incomprehensible ending... In short, it can be followed binge watching and can be said to be good, the production is excellent but the various settings are not surprising. Coordination: Even the shooting scene and soundtrack design are full of no sense of routine. What is it like, especially like the fast food produced by the food industry assembly line: it is not difficult to eat, it is eaten unconsciously, and there is no nutrition and it is really annoying; it is not a big problem that the content cannot pick up the story. The script, sound and light, and service are all very good but little character; even the actors feel that it is only mechanical expression of the script for the design of the character and lack of creation, so there is no emotional connection for the audience to enter the character.
