This show is simply great. The romance is lovely (the two leads have amazing chemistry) though not predominant, as the real theme is the power of media and all its consequences, which is always incredibly fascinating.
Very well written, this show manages to never be boring and always unexpected.
On a side note, this is the second show I watch with Lee Jong Suk (after W) and I liked him a lot here. At the same time, this is the first show, for me, with Park Shin Hye, and I love her! She's really, really good, so much so that I'm definitely looking forward to watch more shows with her! 100% recommended.
