I do not mind interspecies or AI or cybernetic love. Although this was too much.
Maybe they could have told this story in the 24th century or so… The way the IA is portrait is completely nonsense, going from a rational machine learning to a machine with feelings…

STORY – the story is very messed up for me. We have a woman in love with a machine, a grandfather completely driven by power, villains that kill and do all sorts of bad things without being punished, a mother that want to sacrifice one to have the other, a spoiled evil man that becomes good in the end (maybe an upgrade was made), etc.
The plot is not well made and there is a lack of coherence in the way Nam Shin 3 treats and relates with Kang So Bong.
If we want philosophical dialogues and think about this technological future, we have the incredible Blade Runner movie or the short story: "Do Androids Dream of Electric Sheep?"

ACTING – it was very good for most of the characters. I don’t think the transformation from Human Shin to the AI Shin 3 is very big, but Seo Kang Joon did a good job. That was probably the best of the drama. The casting deserved a better story!

MUSIC – I don’t recall any of the songs, so i don’t have much to say.

REWATCH – no. It was painful for me watch until the end. There are some cute parts, a few funny scenes (could have been so many more), but I will never rewatch this again

OVERALL – don’t know what to say. I am a man, I like rom-com and maybe I did not find any connection with the romantic relationship (if we can have a relationship with a robot that don’t feel nothing…). I felt in other dramas of this kind, but never in this, and I really tried.

SPOILER!!!
The last scene killed me! A robot with lacrimal glands?!?!?!?!
I do not get it! Sometimes the ending of the rom-com dramas is so open or with just a scent of what is going on. In this, the writer(s) put a tear in a robot!!!!!!!
