Honestly the story was very good, but personally it got a little rushed at the end it seems. Some of the key information just gets slipped out and some of the people that were helping slowly disappear . Example, Shen Yu's helper. After watching quite a bit of crime drama's, this one didn't scary me as much, and i think the main reason for that is because the scenes were not as brutal as some Japanese and Korean crime/mystery/detective dramas. The acting was splendid and totally worthwhile to watch but i might think twice before rewatching.
