I liked it very much, but (and this is a personal opinion) it was too slow for me. Sometimes the plot felt pointlessly elongated and I admit with no regret to watching a few episodes on 1.5 and even 2.0 speed up and then I didn't feel like pulling my hair out. The actors all did amazing jobs! The idea and plot twists were all spot on!!! It was just the speed of actions I had a slight issue with.
For the first time in a very long while I had absolutely no idea what was happening. The suspense was amazing. It was extremely hard to leave it to actually work, sleep, etc. The acting was great, the plot was great, just over all I'd give 11 out of 10 if I could!
Honestly? If you are into meek, weak, snivelling Fls and well, for a lack of better description, stupid MLs - then this is right up your corner. For me though? - this was such a waste of time, I feel like I lost years upon years of my life. The plot was as well ... just NO, maybe it could have had potential if the main characters was Shin Hoo Ye and the idea of the series was how he deals with idiots.
