First of all, I think that for the most part if you have watched the Japanese version of this drama, it will make some form of difference in what you think about this drama. As one of those viewers who have watched and obsessed over the Japanese version, I was pleasantly delighted with this version of Liar Game. I walked into it thinking that it wasn't going to be as great as the Japanese version, so I was surprised at the different little twists and clicks away from the original. For the story, it very much is correlated with the manga called Liar Game but the drama added some new content. I must say that the setting of it being a public game show is rather nice and the occasional opinions of the public being thrown in was refreshing to see. The music was for the most part suited to the drama. I love the opening introduction to the drama, that is my favorite piece of South Korean instrumental music now. And as for the background music, it did its job of making certain things suspenseful and at other times emotional. Overall in this category, I wasn't too focused on it. Most of us will agree that the damn good acting is what hooked and kept us hooked to this drama. The casters did a great job picking these performers who carried this drama. I'd like to take the time to complement Kim So Eun and Lee Sang Yoon on their phenomenal acting. I would also like to complement the supporting characters especially Jo Dal Goo. Jo Dal Goo's was so on point, oh the feels. I did not find Kim So Eun's acting to be annoying or stupid. As for Lee Sang Yoon, he played the part very well and looked great playing it. But the one who KILLED his role was Shin Sung Rok. I mean talk about swag in a villain role. He was off the charts psychotic and maddening. I cannot imagine anyone pulling this role off besides him and he deserves every bit of praise for his role as MC Kang. To end, the re-watch value of 7.5, believe it or not is pretty high. I've re-watched the Japanese version numerous times and the same is happening with this version. There is something about this story that I love to the inner core. So overall, this drama is definitely recommended! Give yourself some thrill and suspense, and enjoy the swag of MC Kang while you are at it.
