I lived in Hong Kong for over a decade. I wish to say that the setting, mood, and spirit of the series feel authentic. Even inconsequential characters and extras played their part in bringing this drama set in Hong Kong true to life. I can see the producers really cared and know HK well.

This is ultimately a complex drama, that could be set in any city. Characters face moral dilemmas and conflicts. The series does not hold your hand, and leaves you to your own thoughts to decipher what is being said. It's a series you could rewatch and find different details and themes throughout.

Many themes are explored; from existentialism, loneliness, identity, and the meaning of family. Modern themes like what youth in HK are also touched upon.

The cinematography is A-level. It's beautifully portrayed. Hong Kong has many faces. It is both modern and traditional. It is dystopian, yet warm. It has life and vibrancy, but a deep coldness to it as well.
