The first 4 episode was gold. For the first time that have a Korean Drama about the Manhwa world. It is in its odd and was purely interesting. But the more you watch, the more boring it gets. The writer put too much details and twists in one episode, and it is not a smart move at all, audience not only not getting excited for what will the characters would to next but in fact tired of it. The rating in Korean also dropped a lot comparing to the first 7 episode. About the acting, Lee jong Suk acting is good, not phenomenal but ok enough to watch, but some scenes he do portraits the characters really well. About Han Hyo Joo, I really liked her in Iljimae but in this drama, her acting is quite weird for me, not natural at all, but it was ok. This drama is the excellent example of Starting off great but falling back at the end.
