This is a really good thought-provoking series!
The actors and actresses in the drama did a really good job in depicting the stories.
I thought it would be a boring series with the same stories and plots for each deserter. Most detective series I came across with usually bore me because they would have the same plot in every case, they would just be given a case > solving it and had a few problems > then finally caught the criminals, for literally one whole season, but D.P. is far from that! Every character has a deep and solid background, thus showing completely different solutions for each case.
A little side note, I think it's a pretty heavy drama, so if you're easily stressed out, I recommend watching it 1-2 episodes a day, it's pretty effed up.
