A very unsettling drama, as one can imagine that if something like this ever became possible, there would be power crazy dictatorships and wealthy countries happy to abuse and use engineered humans as weapons.
After all, with cloning, growing a human ear on a mouse and even working on growing human organs in pigs, this drama is not total fiction.
There are many very unlikable characters and the usual abuse of and arrogance towards, ordinary people, by those with power and money, is a key part of the story.
Ji Oh reminds me of Frankenstein's monster; lonely, naive and innocent. Sadly that also makes him vulnerable and easy to manipulate by those he mistakenly thinks know best. It's people's abuse and cruelty that leads to the monster emerging. Kim Rae-won was so good in portraying the role.
The character of Gu Reum was really well acted by Lee Da-hee; tough, principled, but ultimately, I found her to be fickle. Ji Oh never hurt her, but loved her and only ever wanted to protect her; yet, at crucial times she listens to those very people that cause all their problems and no end of pain.
To think that she could protect something precious alone and that Ji Oh would be OK with that, was crazy. There were so many things she could have said to him to compromise his mistaken beliefs, but she didn't even attempt it. There are ways around memory loss.
I found every episode gripping and the story well thought out, but the final one was bizarre. That Gu Reum would rather leave something hidden, risking it not surviving, than to tell Ji Oh where it was, I found unbelievable.
L.U.C.A. is the beginning of something altogether quite horrifying ~ not the super humans themselves, but what most likely would happen to them and ultimately, us.
Well worth watching and very thought provoking.
