In my opinion, the film is very good. As always, the actors perfectly conveyed emotions and feelings to the audience so much so that at the end Seo Bok was really a pity... As they say, if an actor makes u worry and feel, then his acting is real!
And also heartbreaking emotions, especially when the film shows that "not a person \ object" in their opinion suddenly begins to experience emotions and understand this world as a person, to experience love, fear, injustice, hatred, to realize that he is already not a real person, the feeling of injustice on the creators is especially high at the same time shown considering how they used him and treated him cruelly, inhumanely, and here you begin to pity "this object" of a non-person, who in the end turns out to be more human than his creators.
Such feelings often appear in films where they create robots or clones or people with superpowers for research and then decide to destroy them because they are no longer needed. Sometimes u start thinking that everyone has a soul, even objects at first glance)
I felt sorry for Seo Bok, it hurt that he understood everything but couldn't do anything about it because he was dependent on injections and he understood it too

He wanted to be useful to someone, to really save his life, so that his suffering in the experiments was not in vain, but not in the way his creators wanted, who were absolutely not bothered by the fact that he might be in pain or that he was eating bad food and whether he was eating at all, they didn't care what he was thinking, he was just a living experiment for them.
In this film there is something to think about and discuss in light of today's events in the world and in everyday life.
For example, that through a film they can also manipulate consciousness, as well as another thing, that more often in a film u will meet humanity and help more than in real life under serious circumstances..
I think this film is more for those who have empathy and can feel others very well, this film shows how cruel people can be in their momentary impulses, as well as the ordinary simple desires of people who are dependent on others not of their own free will, which sometimes can be inaccessible due to the fault of others..
To some extent, this film brings us back to simple human values: to eat noodles, to try something for the first time, to meet the sunset and sunrise at sea, which is eternity in this context, to feel the water, the sea, the sand, which is life.
