49 Days is fresh and very interesting to watch. There may be flaws but you could barely see it. The way the story progress always put me at the edge of my seat. I never watch a drama this good. When it comes to the actors, I commend Lee Yo Won for taking this very challenging role. If you are not following the story very well, you can say that Song Yi Kyung has split personality or worse multiple personalities on the highest level. She was able to bring the quirkiness of Ji Hyun's personality. She should have received a Daeksang for this role. On the other hand Nam Gyuri as Shin Ji Hyun is a very interesting character as well. There are moments when she look like a doll. Jo Hyun Jae as Han Kang is a very vulnerable character. If I were him, I would go crazy over the resemblance of Yi Kyung to Ji Hyun. I love his character here because he was like a martyr. It was hard for him to express his love to Ji Hyun so he somewhat become a bastard towards her because that's how he he deals his pain of longingness. But also he deeply cares for her. (Jo Hyun Jae and Jo In Sung are my favorite Korean actors). Jung Il Woo as the Scheduler, what can I say about his character? He was perfect, he brought a lot of fun and one of the reason why this drama is highly entertaining to watch. Bae Su Bin as Kang Min Ho is quite a dark character and even if he is the antagonist here I love his character, it was well represented. There are moments when I kind of hate him but as the story progress, you kind of understand his character. But still a villain is a villain. The music used in the drama was perfect for me. The production knows when to inject the music that suits the scene. It adds drama, it adds thrill. When it comes to re watching this drama. I would but not right away. Give me 4-5 years and I would want to re-live the drama brings. Overall, this drama never disappoints. Previous comments and reviews I've read are correct. It's quite difficult to put it in a genre. It is something refreshing to watch, something you could never thought is possible. Something you have never seen on TV. The plot is very interesting and the story was very well executed. It was close to perfection. There are moments when you can't help but laugh at the quirkiness of the leads and there are times when you just can't compose yourself over the emotions you got from what is going on. I felt that the funny moments were unintentional but it really works.
