After having completed watching all the episodes I've been wondering what on earth I would say is my opinion about this series. The only thing that comes to mind is "oh, goodness". Unfortunately, that is neither particularly eloquent nor descriptive. However, it is what it is. "Oh, goodness" in all the exasperating and disappointing forms of meaning.
That I finished watching all the episodes is an accomplishment of sorts. The initial episodes at the prison are intriguing and the storyline is different enough to capture attention. However, as the plot progresses to the hospital setting it is where things become lame, and frequently exasperating.
Let's start with the characters: my "favourite" was the mother and chief of the anaesthesiology department. You couldn't pick a worse character, casting and combination of the two. Cast a young person to play a stiff 50-year-old with fake grey hair, expressionless and stern in a dumb way - and all you get is a big fat fail. The nurse and the prosecutor fail in their own ways as well. The female lead - well, I still can't make up my mind if the issue was the actress, the storyline or the direction because crying at everything and nothing was just lame and frequently cringe-inducing.
The male lead was good, surprisingly so for such a mediocre cast and plot. He carried the show and made going through the episodes bearable. However, the ending was quite a disappointment and in many ways far removed from the reality of how actual humans would react in the same circumstances.
