I just watched the entire first season and the second season is due out next month. I was just told about it and it really peaked my interest when I was told it was about a guy that kills people that deserve it (i.e. child molestors/murderers, drunk drivers that kill people in crashes, etc.). His character is a forensics expert but also psychologically fucked up and feels the need to kill. The only way he justifies it is by killing people who deserve it, like taking out the trash. This is a great show. It's on Showtime, so I'm going to have to wait for the DVDs.
