i'm so happy i hadn't read the reviews before watching it, otherwise i know it would have some influence on me. I like this drama very much, actually, i binge-watched it, which has never happened to me before. yes, there are some points when the drama slows down a little bit, and the reason why Black Bridge Valley Village had been shut down is somewhat forced and not so shocking. I think the music doesn't match with the story, except for the intro, there is nothing else that bothered me so much that it needs to be mentioned. it got me from ep 1. if you like Signal, give it a try. I watched it because of the writer, although i haven't seen Kingdom, really not my cup of tea.
