First, I would like to apologize if I will hurt the feelings of some Park Eun-bin's fans. Basically, I am a PEB's fan too, but a kind of weird fan who allows himself to be critical about the productions where she leads in. Second, as concerns "Castaway Diva", I want to say from the start that my criticisms are not concerning the acting but the screenplay. PEB is sincere and expressive in her acting as expected, and the other actors are sincere too, but the screenplay is contrived and does not provide a sound basis for an outstanding performance. The spectator hardly knows what is the main direction, the main issue this series is aimed to, so many things are mixed up.
Apparently the main message the series intends to convey is that one must always stay focused and optimistic in order to attain one's goals. The message is right but does one really need all this overcomplicated and overemotional story to express such a straightforward idea? In order to deliver a positive message there is no need for big effects like being stranded on a deserted island, pursuing an idol career, or facing a psychopath. Positive thinking can also be transmitted by a drama about problems of ordinary people in ordinary life.
The series has also the ambition of addressing domestic violence. It is a very important societal issue and it is worth bringing it to the large audience. But does one need all this musical and romantic packaging to deal with this issue, is the improbable story of Seo Mokha a proper ground for that? Or does the caricaturally bad character as that of the pathological father provide the necessary sobriety and authenticity? I don't think so.
Another potentially interesting aspect of the series is the re-integration of a person who has been isolated for a long time. The struggle of such a person to regain a place in the society may be a very good story line. But the story has to sound true and not made-up. Is pursuing the ambition to become a pop star actually convincing? Is falling from a ferry and having been stranded on an deserted island compelling? Is an ex-fan and fallen-idol relationship appealing? For young people following today's pop culture, maybe. For me, from the elder generation, it is not.
In fact, in my opinion, the screenplay of "Diva" is not following a consistent scheme but simply pulls on all possible strings, including a story of a come-back of an idol, family pathologies, singing of the star actress, romance, in order to get the strongest emotional impact possible and to attract the widest audience possible. The series is overloaded with melodramatic situations, the weakest part being the love triangle, the hidden identities and the revengeful father. Nevertheless, PEB and her fellow actors were able to transform this mere entertainment product into a touching and audience gathering show.
I willingly admit that among the nowadays films and series, where the most popular are thrillers, horrors, violent crime or war stories, heartwarming and positive series like "Diva" are truly needed. However, I think that PEB, at this stage of her career, desserves better scripts or simply another type of scripts. She said in an interview that she would like to try different genres of films. I hope that her next production will not be a romantic comedy, but rather a psychological drama. I would like something more subtle, contemplative, introspective, even melancholic, without any excessive melodramatic effects.
