"The World That They Live In" takes you to an emotional roller coaster that will make you think of getting off somewhere along the ride, but at the same time, will have you anticipating what's next! It definitely lives up to its title as it truly takes us to "the world that they (production staff, crew and team) live in", and I think, that's one of the most enjoyable part of the show. It gives us a glimpse of the real life drama of the people behind the dramas we love to watch. The story of this show does not only focus on the lead actors, Hyun Bin and Song Hye-kyo. It also dedicated some episodes about the supporting actors, which I found fun too! It gives depth to the supporting characters and again, gives us a glimpse of the dramas in the lives of actors / actresses, story-writers, scriptwriters, chief directors... and other people involved in the production as well. However, the story of the main actors was a bit frustrating! The conflicts between them and within each character seem so shallow, and you would want to hit your laptop screen several times. Still, both Hyun Bin and Song Hye-kyo's beautiful faces and good acting skills will keep you from doing so. Besides their incredible beauty and acting, Hyun Bin and Song Hye-kyo's chemistry will make you go crazy. "The World That They Live In" is not perfect. It will also be frustrating at some point, but trust me, the end will make you wanting for more.
