With rabid fans screaming his name at concert halls everywhere, Rain is the hottest export to have come out of Korea since kimchi. With four top-grossing albums, a sold-out concert in New York, and extravagant ticket prices to his name, the time seems right for his debut movie appearance.

Riding this wave is director Park Chan-wook in his first romantic comedy outing "I'm a Cyborg But That's OK". The movie starts off showing Yoong-goon (Im Soo-jung) working at a factory assembling radios. Thinking that she is a cyborg, she cuts her wrist with a knife, inserting wires into the wound, totally oblivious to the pain, plugging the other end into an electrical socket. Besides getting herself a devastating electric shock, she also got herself admitted into a mental asylum.

To make things worse, Yoong-goon refuses to eat any food because she thinks it will kill her, and as a result she becomes weaker day by day. She also develops a grudge against the folks in white coats, for the sheer fact that they admitted both her grandma (who also happened to be clinically insane) and herself into the asylum. Enter Im Soo-jung (Rain), a fellow occupant in the asylum who has the 'power' to steal other's traits and personalities.

Yoong-goon originally wants Im Soo-jung to 'steal' away her 'compassion' so that that she can murder the doctors in the asylum, but Im Soo-jung, who initially complies with her, later realizes that she needs help and sought to find ways to make her eat again.

The movie starts off on a promising note, bringing colour and life to the drudgeries of the mental asylum by introducing an assortment of wild and wacky characters, which are fun and interesting to watch. Amongst them is a man who feels so sorry for himself that he can only walk backwards, a lady who looks at her own face in the mirror 24/7, a woman who thinks she can fly by lying on the bed and rubbing her feet together, among many others.

The momentum, however, is lost about midway through the movie. The film tries too hard to be funny, and as a result it doesn't stay serious when it needs to. In the end, the audience has difficulty connecting with the main characters. The movie, which is supposedly about Yoong-goon's search for a purpose to her existence as a cyborg, fails to reach the emotional heights that would have made the story much more engaging.

"I'm a Cyborg But That's OK" is essentially a light-hearted romantic comedy that might just touch a few hearts, if only slightly. Nonetheless, the performances of Im Soo-jung and Rain as love interests are charming enough to make it entertaining enough for fans of Rain and of Korean dramas. But for the rest of us though, it is OK to give it a miss.
