I almost cried a few times throughout all 12 episodes. The show is mostly an intriguing detective story, but has some nice humor sprinkled in as well as plenty of heartfelt, touching moments.
It's a little slow at times, but it's all worth the payoff, and there is some intense moments where you think "omg not now!" or "no no, can't be!". All in all, a great mini-series, well worth watching.
