Hands down, Lee Min Ho's portrayal of Lee Gon is very good. I understand why people said it's a different side of him compared to his past works and I've seen them all. That being said, my low rating of this isn't due to his fault- it's the script. Everyone was talking about how the first half of the series was slow and the plot lacked substance- I agree. I found myself watching most of it in 1.5 speed and still manage to read the subtitles fast enough and shrink my 1.1 hours down to 30 mins. K dramas are very good at creating suspense and building tension- at least from the ones I've picked to watch. I've never been really disappointed in a k drama when I choose one to watch but this one was just begging me to get to the end fast because I was bored. The latter half was better but then the tension would be lost. The romance part was beyond disappointing- absolutely did not feel a thing from their chemistry (if any). We went from, zero interest to interest in a matter of one episode and I'm left with, huh? I felt more from Lee Gon and Yeung's interaction than anything.
