I preface, I first watched this drama years ago and recently rewatched it as before I loved it but found it aged terribly.

I'll start with the pros, it's visually well done and the shots are some of the best seen in an action drama. It starts with a very promising premise and the first set of episodes, and for a while the acting is great.

The cons are that it goes downhill and lacks something that makes it unique and a good watch. I find the story quite erratic and hard to follow at times, and I feel like there are too many plot holes for me. I also wish the dynamics of the main leads were better because they do improve and it's frustrating. Also, the ending is well, not the best in my opinion and a season 2 is definitely needed for it to work,

Overall, I think it is an entertaining drama though and is showing promising talent within the film but not enough for it to be well, considered good, so I would simply consider it average.
