Loosely based on Little Women is the sort of loose that happens when the elastic in your trackies gives way and they drop to your ankles in a wrinkled heap. Yes they are still trackies, but not obviously so. I spent the first episode distracted by trying to unsuccessfully work out how this drama maps to the book. But I was looking in the wrong place, because, although there are parallels to be found, the map is really in the theme: the significance of money.

This is fundamentally a story about money and its sidekick—power (the perennial obsessions of K-dramas, well maybe most dramas actually…). How and why it shapes lives, morals, choices and character. How poverty shapes your mentality and expectations. What you are willing to let it buy and what that does to your integrity. What risks you are willing to take to acquire and keep it. Under what conditions you will let it go. The price that your decisions exact from both you and those around you.

It puts the protectors, helpers, underminers and benefactors of the wealthy centre stage and examines their motives and desires. This is a rare perspective and I can only remember it being the centre of a drama in one other totally brilliant case, “Secret Love Affair” (if you are interested in this aspect, watch SLA, it will not disappoint, although it’s not a thriller).

As you can guess by now, it is not the plot that makes this drama special, (more about that later) although you can simply watch it as a thriller. It’s the examination and unfolding of motive behind the fight for freedom and opportunity in a world that values money over the individual. A society that insists we fight for limited resources to fulfil not only our dreams but our basic survival as well.

It’s almost impossible for us to imagine a society not based on money. But money itself is not of course concretely real, it is simply a universally accepted system of sharing resources that becomes meaningless if we lose trust in it. It is the illusion around which our reality and dreams are built. And if you are going to be fanciful, you could watch this drama as a commentary on the system’s strengths and weaknesses and the approach people take to best work it. Given that it is compulsory to engage in this system, the question as to what is morally acceptable and what is personally justified is core to the unfolding of the narrative.

Having said all that, there are problems in my opinion with how the drama is written and presented. There’s a vibe of the sisters being ordinary people (a reference to Little Women perhaps) who are unwittingly and sometimes unwillingly mixed up in something big.

However, through most of the drama, the sisters don’t display enough realistic, long-term emotional reactions to support their ordinariness in the extraordinary and violent situations that surround them. In a normal thriller we suspend disbelief because the whole thing is not related to any recognisable reality in the first place. Here, particularly in the middle section, I am being made aware of the gap between quasi normality and the world of the story with the result that I am also very aware of suspending my disbelief. And at times I found the approach is not subtle enough to make it work.

Because the women are presented as relative amateurs, there are moments that stretched my credulity to breaking point. For instance, without any preparation and seemingly without backup, they are willing to confront people they think are probably murderers. There are scenes where professionals who would never disclose information to anyone let alone the naive woman in front of them, disclose it. Etc, etc.

There’s an odd mix of the ordinary, the extraordinary and the completely surreal. The more surreal it gets the less the ordinary women at the heart of it are credible. It turns into conspiracy theory central with hallucinogens thrown in for good measure. Whether this was intended as a reflection of the madness that money creates in people is debatable.

The plot gets increasingly bizarre and takes off in strange directions and at times loses impetus. This has a fragmenting effect which leaks tension and can be frustrating. But at other times the sense of confusion and powerlessness is very effective in putting you into the shoes of the protagonists.

Overall, this is an ambitious drama and when it works it really works, and when it doesn’t, it really doesn’t. I’m someone who is prepared to put up with stuff not always working well if an attempt is being made to experiment with something new and different. I think this drama tries to do that, so I was happy to give it the benefit of the doubt, but even my goodwill was tested beyond its limits by the end.

What my rating means: 7+ A watchable drama, but nothing exceptional. Good enough to qualify for the race, but finished with the pack. The sort of thing that promises more than it delivers.
