Good cast but really came for Park Sung-woong who I adore but sad to say, even he could not save this drama for me.
This is the first time I have given up watching a Korean drama at episode 4. I know the FL has received a lot of flack (not my cup of tea either, I must admit), but the script in my opinion fell flat on what the drama was really about. It was disjointed.
Had they made it an action drama, I think it would really have come out an 8.5 in my book. The two action scenes leading up to episode 4 were great and Park Hae-Jin really really excelled. However, ‘comedy’ was constantly thrown into the stir fry pan and for me the script became over cooked.

The other reviewers have said it all so I will make it short.
My best moments were the action scenes and watching the trailer.
