It took forever before the story started progressing. It could've been easily condensed down to 7-8 episodes without sacrificing anything. The amount of plot convinces was unbelievable. A common example is whenever a piece of information is about to be revealed, it magically get sabotaged in the most blatant way there is. Throughout the entire drama it felt it was building towards something big but it never got there and the resolution of the culprits was underwhelming anyway. The drama in general was riddled with all kind of problems but the big cast was pulling it up so damn hard....
