What would you do if you were faced with a robot who showed some humanity ? Would he be just a block of metal to you or would you start seeing him differently? What if he showed more humanity than you? I won't give any detail about the story, I'll just say, this drama was RIDICULOUS! Rarely, rarely has a sci-fi production moved me but this one is so creative, different and bold. Seo Kang Joon is my new hero. It takes a special artist to give life to such paradoxical characters. I really really didn't expect much from this show but I was blown away from start to finish. The cliffhangers are insane, everyone's performance is on point, the story is impressive and besides a couple of cliche elements (which I absolutely don't complain about - all genres have their formulas), it was unpredictable. Gong Seung Yeon is a very talented actress, and did an excellent job here. The only reason I'm not writing much is because, I have so much to say that I know somehow I would end up spoiling. Jo Jung-joo writer-nim? I don't follow writers, but I'll be stalking this one. All I can say is : WATCH IT, Re-WATCH IT, buy the DVDs if you can support it, wear the T-Shirt, buy the MUGS, tell your neighbors about it! Definitely one of the BEST dramas I've seen to date, and one of the top 3 dramas of 2018.
