I really don't understand all the hype about this drama. Personally, while the story had a lot of potential to be great, it was full of holes and inconsistancies. There were several times throughout the drama when I was left wondering why on earth certain decisions and actions were made by the characters. A lot of those decisions and actions made no sense. I believe the writers to have relied too heavily on shock value and cliff hangers, at the expense of plot consistancy. It was kind of messy and predictable. So why give the drama a 7/10 and not lower? Yeah, I know my opinion on the writing is harsh. What made this drama interesting and kept me watching was the superb acting by the cast. They were all wonderful. So wonderful in fact, that I can't even choose who stood out more. Every actor was exceptional. I can recommend this for those looking for a good, gritty action drama with great acting. Just be prepared for the flaws in the plot.
