The thing I found most annoying is the villain Seo Jong-gil. He magically happens to spawn whenever someone is talking. He was everywhere. He was a master-class eavesdropper. I mean how is that even possible? He knows and understands things very very fast.
Meanwhile, the ML can't even hide the kill switch. Who the hell hides the thing that can kill them, in plain sight, just like that? He said he was a very intelligent robot but couldn't even hide something that was really important.
Nothing much happens to Seo Jong-gil. After all that he did, it feels that he still got the last laugh. He was not even hit, not a single drop of blood. At least his limbs should have been broken. Even till the very end he was winning. He never even faced any public humiliation.
The last episodes were definitely stretched and because of that, they rushed the ending.
The ending scenes were completely emotionless. After seeing how Seo Jong-gil was still causing trouble. The ML and team were not able to get him back or even stop him. The last episodes all felt emotionless to me and also pointless.
This was a great drama, the first drama to actually make me shed tears. But because of my hate towards the villain and how he never suffered much. I now hate it.
The ML and FL did a great job in showing the emotional scenes in which the robot says how he is just a robot without feelings and all. I really felt those moments. The OST really helped in bringing in the emotional effect. But unfortunately, the ending ruined everything for me.
