Ok I'm gonna be honest. I just watched this for 张译. But!! The story isn't all too bad, although it /is/ a bit of a slow burner compared to other crime / war dramas. I personally like that, cause then I can miss like four episodes and I won't be super lost when I skip parts, unlike other dramas where I turn my head for five seconds and miss a major plot point. But when I say it's slow, I mean SLOW. I accidentally fell asleep to this thrice because of how slowly it was chugging by, but the story isn't necessarily boring. As for the music, I do like that they tried to use a more traditional orchestral soundtrack, which I did enjoy; it's just the more digitized music that kind of distracted me from what was going on in the show. The acting was decent too--I didn't have too much to criticize on that aspect. Overall, I think this show's an acceptable watch (especially while drawing ngl).
