If the goal of the film was to demonstrate how many people treat others as less than human, then the film succeeded in its goal. If the goal was to demonstrate that we should treat everyone with a level of love and respect as human beings, the film comes up a bit short.

Kim Sun Yi is a young, and rather sickly girl, living in a very small, rural village with her mother and sister. We can see her life is rather mundane, and she finds small pleasures in writing until she comes across a South Korean experiment gone wrong.

Enter Cheol Su, a young man in his late teens who has been locked up and used in some kind of backward experiment with animal and human DNA. Initially, all Sun Yi sees is a wild animal who eats like one and largely behaves like one. Her mother takes the boy in, and cleans him up, even though she’s unsure of what to do with him.

Sun Yi is initially disgusted by Cheol Su’s lack of table manners until she finds a book about how to treat dogs. She uses this book to train Cheol Su to only eat upon her command. We find that Cheol Su can understand Korean, due to the professor who was raising and experimenting with him. Whenever Cheol Su does something correctly, he gets a pat on the head, much like a dog.

Seok Ji Tae is the town rich boy and thug. He owns the house that Sun Yi’s family is living in. He’s a largely uninteresting and rather cliched villain of the story, which tends to play out like a Korean version of “Beauty and the Beast.” Of course, Ji Tae attempts to brazenly demand Sun Yi’s affections and becomes violent when he doesn’t get them, making him a far greater monster than Cheol Su could ever be.

The film is a touching one and the performances, especially by the film’s two leads in Bo Young Park and Song Joong Ki are especially poignant. However, the chemistry goes little beyond the affections of two people, but rather a woman and a man she perceives as an animal (even if a benevolent animal at that); like a beloved pet.

The story would have been better served had Sun Yi begun to see Cheol Su as a person, and yet she’s never really one hundred percent sure. In the end, she says that she doesn’t care if he’s a monster. It would have been more powerful if she had told him that she knew he was a human being and not a monster. His violent actions are always done to protect her as well as those around her, but she’s unable to truly see past his animalistic qualities.

In the end, despite living alone, we see just how wrong Sun Yi was about Cheol Su. Just because a person doesn’t speak, doesn’t mean that they can’t, and perhaps she learns something about how to treat others. This film had the potential to be so much more than it ended up being.
