So I'll start with this:
I'm a mature 12 year old.
I started watching this series a few days ago- and I'm addicted.
This TV show is great, but there are many things that parents should be concerned about:
Violence- practically every episode is violent, gory, and graphic. Every episode shows a corpse. Often times, the corpses are not very kind to the stomach. I've seen bloody corpses, corpses with twisted bodies, corpses squashed to death and more.
Sex- Many suspects and victims have weird sexual fetishes. Often times, sex scenes are pictured. There are some sexual references too.
Language- the words a** and b**ch and more are often spoken, but the f-bomb or s-bomb hasn't been dropped.
Drinking, drugs, and smoking- There is smoking, drugs, and alcohol shown/mentioned in many of the episodes.
There are positive messages and good role models- detectives try hard to catch the people who commit crimes, and some characters are nice people who do good stuff. The main positive message is that people who do bad things should be punished, and justice should come to those who are victimized by them.
So overall, the main problems are the sexual content, the graphic images, and the drugs and drinking.
This is an awesome show with good messages, and I definitely recommend it to those who can handle the inappropriate content I previously mentioned.
