And here it comes: Me critisizing this overly hyped drama. Don't get me wrong: This is still a very good drama worth watching and it is totally outstanding in some aspects... but not so much in other. I will start with what bothered me and why I cannot give it the perfect marks everyone else is throwing at it. Later, I will list the totally awesome things about this, so stay with me. What there is to critisize: The black-and-white-setting. If there was ever a story about how incompetent cops are, here it is. It is the pinnacle of unworthy police work, because this exactly is the basis for the entire plot. All police-men (but three), are depicted as either corrupt, lazy, incompetent or plain evil. None but the main characters do their work properly. Of course, there ARE bad cops out there and corruption and everything, but man, this drama just divides them plainly into good cop and the rest. Thus, from the beginning, I got unnerved by unrealistic behavior and "Oh no, who in their right mind would act this way?". It kept me rolling my eyes. The script was written like an inverted fairy-tale about a very bad and dark world where the good people are a minority and most is awful. Because the drama shows very openly and very early who thevillains for the main plot are, and after a couple of episodes of solving several distinct cases this becomes the main focus, any surprise about this goes down the drain. After episode 8 or so everything became predictable for me (but one point, listing below with the positives). Then there is the thing with the walkie-talkie. It will be mentioned in the positive-section below, but it still has a flaw: As many plots which play with time, this too, makes some mistakes. People who are into logical plot development and know the problems of changing-things-in-time-stories will know, what I mean after watching it. It just could not have happened the way they showed, but this is a minor flaw. Here comes the positive: The directing and cinematography are INGENIOUS. Whilst everyone gets hyped on the (for me unperfect) plot, the real masterwork lies in everything else! It is marvelously shot, the colours, the cuts, the directing - they are flawless and on the level of high-grossing Hollywood productions. Absolutely superb! In this aspect alone it is better than any drama I have ever seen. It delivers the tense and dark athmosphere absolutely believable. And the acting is topnodge, too. Whilst the plot about most cops being junk falls short and later on becomes predictable, what kept me going was the mystery of the walkie-talkie. Yes, the thing with the time isn't quite perfect, but the question Why do these transmissions happen? puts you on edge. Altogether a very good drama, for sure, but seeing the ratings a bit overhyped IMO. But you ought to give it a try!
