One of the best series I saw this year. Every beginning is hard. But when it's about to changes the people's' way of thinking is harder.
The plot is very interesting and reflects, probably, a harsh reality. There are crazy people in this world, serial criminals, who want only to kill. On the other hand, there are people who can go deep into those criminals' hearts and minds and manage to catch them. It is a very hard job to do and very dangerous. At the beginning nobody knew what a profiler is. And at the end I saw a strong team, officers who managed to change their way of thinking, to understand that a change must be done in their way of working and to adapt themselves to that new reality in order to catch the criminals. A powerful game of minds around a terrifying reality.
I had moments when it was hard for me to watch. So much darkness in those criminal minds! Watching what they've done made my heart tremble.
The script is a masterpiece. I had not even a single moment of boredom watching this series.

Acting/Casting: There is not much to say. They were wonderful! I hated all the criminals and I loved all the officers. That means all the actors did an excellent job! With a script like that their acting was almost perfect!

Music: It was according with the plot. And it fit perfectly.

Rewatch value: I will re-watch it for sure, but not right now. There are so many good ideas I want to re-watch. Human psychology is something that I like and this movie shows plenty.

Overall: This series is not for everybody. It's not a light series. But if you want to see something that challenge your mind and heart, do it! You will not feel sorry! Guaranteed!
