This drama was absolutely breathtaking. It is definitely my favorite drama. Here is what I've loved about it.

The Ost
The music was simply wonderful. It captured the mood really well. I actually downloaded all of the songs from Are You Human Too? It was really amazing :)

The Acting
Seo Kang-Joon (Nam Shin and NamShin3) really captured each of the characters wonderfully. It was like he was two different people. The way he acted as the kind and loving NamShin3 and the angry Nam Shin made me want to watch more and captivated my attention. Gong Seung-Yeon(Kang So Bong) showed me what it is like to love someone unconditionally. She played her character really well. She didn't judge NamShin3 by the fact he was a robot. She accepted him just as he was. She didn't worry about him being a robot and she encouraged him to be true to himself instead of discouraging him to be someone else just because he was different. Every single one of the characters played their parts amazingly. They made the drama so much more enjoyable and full of suspense and drama.

The Story
The storyline was written really well. It really did make me cry when something bad happened to the protagonists. It also made me want to jump into the screen and hit the antagonists when they did something cruel. It kept me in suspense. The ending was written really beautifully. It made me content but has also made me wanting there to be a season 2 ;)

Overall this drama is the best one in my opinion. It had the suspense, the drama, and the romance in it. I definitely will rewatch this drama and I highly recommend 'Are You Human Too?' to anyone and everyone. You will not be disappointed :)
