I watched the whole drama for 3 days only. I discovered it after watching Flower of Evil. And I have not seen the original Criminal Minds.

I believe that the drama's focus is on the stories of the killers, investigation, and the crime process. It's not about the character development, love story (there's none), etc.. So, you wouldn't see these in the drama. (Although, there are some scenes that do show them).

I've seen a lot of negative reviews on this drama but I think as long as you are more into crimes than character development, this should be a good drama for you. Also, I forgot to mention that this is a really cool drama for people interested in psychology- I'm not sure if they are accurate, but they are believable.

*Flower of Evil is definitely a better drama, so if you decided to drop this, watch that!
