I've been watching this show on Netflix and I can say that it is very, very good. The acting is decent and the storylines for each criminal (as well as the plot for the whole show) are very well written. Alas, it can be very gory and even a little disturbing and hard to watch at times. In the beginning of each episode there is a clip about the criminal the episode is based on, and a few of them are a little disturbing. So far in season one "The Good Samaritan" is probably the worst. He is a serial killer who goes after abusers, but doesn't fully kill them so first-responders can get there first, yet what he does to his victims is a little unique. Don't be fooled its not as bad as something like Silence of the Lambs where the serial killers are extremely gruesome, but I think that the writers and directors can put into TV-14. So basically: great show, appropriate for mature teens and tweens who can handle gore.
