Please be warned that this review contains spoilers. My focus in this article is primarily to consider the writing of Jo Kwang-jin. He is the author of the webtoon upon which "Itaewon Class" is based. He also wrote the script for the series.

Kwang-jin has done an exceptional job. I am full of admiration for him. The drama is intelligently written and sequenced with flair between main-story, back-story, side-story and parallel-story. A number of his characters are quirky and they enliven the entertainment. All the main characters come from a position of social weakness. For example: a black Korean who continually has to authenticate his nationality, two sons who are emotional casualties of a ruthless and domineering father, an illegitimate child, an orphan, etc.; even the billionaire villain was a starving street-child in his early years.

I was particularly impressed that Ma Hyun-yi, one of Kwang-jin’s characters was transgender and that Kwang-jin allows her to shine brightly in the sun. This is a major moment in Korean dramas given South Korea’s continuing reluctance to celebrate that, just like skin-colour or eye-colour or height (etc.), gender identity is a characteristic with which one is born and that ‘normal’ is a word that covers many possibilities. The events that culminated in Ma Hyun-yi’s coming-out as transgender on national television were riveting viewing, and the script and Lee Joo-young’s acting were superb. Anyone who watches this scene with a humane mindset will be emotionally touched by seeing what unconditional love looks like between genuine friends who sincerely care for one another and who see deeper than a person’s surface.

Park Seo-jun is one of my favourite actors and, in this role, he shows the depth and breadth of his abilities. As the lead actor, Park Seo-jun creates a Park Sae-ro-yi who is an uncomplicated man and who stays true his friends 100% of the time -- he never blames nor criticises them. This seems like a simple acting task on the face of it but as one follows Park Seo-jun from episode to episode, it is easy to appreciate that in acting Sae-ro-yi, Park Seo-jun has to dig deep. Sae-ro-yi wholeheartedly trusts those around him and he leads the cast when it comes to demonstrating unconditional love. Sae-ro-yi also never hesitates to accept responsibility however heavy that burden will be. Kwang-jin’s life-philosophies that are delivered to the audience via Sae-ro-yi are truly a gift to the world. In Park Sae-ro-yi, Kwang has created a template for what constitutes an immensely decent human being. It would be a wonderful world -- a really wonderful world, in fact -- if there were more people like Sae-ro-yi around.

In addition: the makeup is first class (watch how Jang Dae-hee ages and becomes increasingly ill); the soundtrack is exceptional and deserves special recognition; all actors create believable and authentic characters; the direction and the production are magnificent. I must also make mention of Ahn Bo-hyun’s acting. His performance as Jang Geun-won is incredible. I have never felt so sorry for the bad guy as I did for Geun-won. It is to Jo Kwang-jin’s writing-credit and Ahn’s acting that Geun-won comes to life as such a deeply flawed character with whom the audience can feel angry, sad and sorry. I never stopped hoping that he would see the error of his ways and change.

There is no doubt in my mind at all that any viewer who watches this show will we richly rewarded if they look beyond simple entertainment and straightforward romance. This is a memorable and outstanding drama. I anticipate that many awards will wander its way. I don't normally re-watch shows but I might make an exception for this one.
