This one is not for the faint hearted, but if you can stomach some relentless violence it’s definitely worth watching. I’m someone who doesn’t like violence much but I was prepared to watch because it was honest and presented realistically without glorification. It was straightforwardly nasty and brutish and the after effects were carefully and realistically created and maintained. However I did find it pretty tough going in places.

Initially set in a dog-eat-dog world of the prison, the character Kim Yo Han does what he has to do to survive. There are no cool heroics, he is at the mercy of vicious overlords and is accordingly vulnerable. This is a stellar performance by Kang Ha Neul whom I last saw in “When the Camelia Blooms”, where his performance also shone like a diamond (even though his character annoyed the hell out of me).

I really liked the writing for this show, whilst maintaining the style of the revenge thriller, it dug deeper into the underbelly of how that anger and pressure both shapes your strengths gnaws away at your integrity. Kang beautifully portrays the anxiety levels and edginess that is an ever present factor in his character’s life. He flinches when doors open and spins to face anyone who approaches him. It draws you into his vulnerability, raising the stakes and the tension and gives insight into the overwhelming pressure to survive.

What this production does in spades is to build and sustain tension. Along with the main character, for a lot of the time you are in the dark, but the threats keep coming from all sides. There was a great balance between the viewer experiencing suspense because they didn’t know what was going to happen, and the viewer creating the tension all by themselves because they did know what was going to happen. This is a writer who knows how to exploit all the angles and does so with a confident touch.

The writer layers character and plot in stages, the emphasis shifting and with it the whole focus and tone. The pace is slow enough for character exploration, but fast enough to keep the interest. Most of the time my hold on the plot was tenuous, but thanks to clever writing, I was keeping up sufficiently to be carried along. Some of the plot twists were obvious but the motivation behind them was obscure and built into a web of hidden connections. At one point Oh Soo Yeon (Lee Yoo Young) says “All of our plans are entangled. If one thing goes wrong then the rest will falter.”

However, the plot can be criticised for over-complication. In order to help the viewer keep abreast of events there is a necessity for frequent use of infill flashbacks to conversations previously seen as well as totally new ones that reveal missing pieces of the jigsaw essential to understand the immediate action. This can feel somewhat clumsy and explainy and interrupts the flow. Also, I did get wearied about three quarters of the way through when the only thing to expect was twist after twist which in itself makes things predictable. As a viewer I was in need of some plain sailing and somewhere stable to lay my allegiance.

There is good characterisation all round, with plenty of ambiguity about good and bad. Along with a stunning performance by Kang Ha Neul other standouts in the cast were Kang Young Seok, Lee Yoo Young and Heo Dong Won. But the standard of acting from everyone was very good as they were given a quality script to work with and a director who didn’t overplay his hand and allowed the dynamics of the story to flourish.

The cinematography is unobtrusive but skilful with a good use of angles and minimal light sources which creates an effective and moody interplay of shadow. It enhances the action without distracting your attention, which in such a complex thriller is essential. Nicely done.

Nothing in the soundtrack stood out for me, but it was sufficiently good to blend into this excellent production without jarring.

Overall, the script, direction, acting, cinematography and editing align to create gut clenching tension in abundance. Even if you don’t know how to play poker, don’t worry it still works.

What my rating means: 8+ A great drama with interesting content and good writing, direction, acting, OST, cinematography. But didn’t quite have the requisite sparkle to bump it into my all-time fave list. Worth watching.
