I have been going through the works of Lee Jong Suk and I had previously thought that nothing could top W for me but this might just have done it. I will attempt to remain as spoiler free as possible in my review. The plot is really interesting and keeps you on the tips of your toes. While the focus on the Pinocchio syndrome and the importance of truth is a large part of the plot, the title of this show does not do justice to the true driving point of this plot. Brilliantly mentioned offhand at the start of the show, the six degrees of Kevin Bacon and the idea that you may not be so far removed from a stranger as you thought is what provides a beautiful tension in this show and will keep you on the edge of your seat. The acting is fantastic and really lets you get to know what these characters are thinking and feeling. Lee Jong Suk is once again playing the role of man whose family died under unexplained circumstances who is searching for answers (such a specific type cast) but this doesn't mean that he doesn't bring anything new to the character. On the contrary, I found myself most drawn to his character in this show over his others, partially because he felt the most human to me. The main female lead is as equally well done and shows that it is possible to be a strong and brave character while still having vulnerabilities. All the supporting cast was fantastic and were never treated as fodder. Each character was well developed. The main villains of the show were astounding. Kudos for providing villains that still maintained human traits and flaws. My one complaint is that I didn't particularly find any of the OST that exciting. Compared to W or I Hear Your Voice which I had just watched (I told you, I'm going through all his shows) none of the songs got stuck in my head the same way. So, that is a little disappointing. But, its not enough to majorly detract from the show. And, I plan on rewatching it many times. :)
