I gave an all 10 for everything because this drama is no joke. The moment I started watching this, I was hooked. Watching an airing drama with this kind of genre could make you go crazy thinking and guessing what could've happen and such. But it was FUN, don't get me wrong. The story was actually common but the intensity and the attack they did was very different. There were twists in each episode that you wouldn't expect. And each episode will give you a roller coaster ride. Acting wise, you have no problem especially with Ji Sung. He is exceptional. I strongly believe he deserves the Best Actor award in the Drama Awards at the end of the year. Also, the kid who played as Ha Yeon was totally good. A promising child actress! Um Ki Joon too was a great actor. At first I was confused if he really had a twin but no, it was just him who played two roles. You would know the actors did a good job when you're attached already to the point of hating them, loving them, pitying them, etc. Lastly, the friendship that was built inside the cell was so precious. You'll definitely love them. It reminds me of Miracle in Cell No. 7 all of a sudden. SNSD's Yuri was good too. She proved that she could act but can be better in her future dramas. All in all, it was a 100000/10.
