Just bought and watched this on DVD. Up until the last episode I was enthralled with the story.
The mixture of journalism, politics and police work made for an interesting mix, although the latter two took more of a back seat nearing the end, replaced with lover's quarrels and artificial exposition more similar to soap opera writing.
While the cinematography is fairly average, the casting and acting is superb.
If you want a suspenseful thriller this one should entertain you, just don't expect a satisfactory ending.
I'd give the show 8/10, but the horrible finale totally undermined the story's credibility with several loose ends, and I was left frustrated instead of with the great feeling I had during the first 5 episodes.
