I understand the casting is not great. But the story is not bad at all. Not totally outstanding but very reasonable flow and pace of story. The way it fills up the events in a later episode was handled good. Maybe hard for any "straightforward" viewer. I find it intriguing. The stories are close to reality in Hong Kong. But who would expect watching TV shows for exactly real story every time? I'm not sure how many review writers understand Hong Kong culture when they said the story is not realistic... i personally have a lot of plus for having a story in Hong Kong and make it as an international TV show. It totally not easy as "interested in Hong Kong" audience is not a lot. Hong Kong is so small. Prime is more for HK expat mostly ha... but Hong Kong needs that...and plus "human trafficking", also needs our attention too. I salute the team to choose a story based on Hong Kong even they know it's limited audience. And try to make it international. If they can broadcast in HK, I'm sure at least HK ppl would like to watch it. Just anyone living in Hong Kong is not allowed to watch it.... i think it's a fairly ok TV series as story for anyone doesn't have a bond with Hong Kong or not interested in Hong Kong. Certainly not a bad one if you can overcome the Botox and focus on the story. Anyone has a little tide or interested in Hong Kong would find it very special.
