So.. you little vermins thought that HH left the planet. No such luck!
Here´s some ranting and raving about..
The series is about one Dexter Morgan, the handsome and all-around nice blood spatter-analyst working for Miami police department. He has an unusual "thing" for blood.. in fact he is totally and absolutely fascinated and obsessed with it. And this is not just professional interest.. He also takes his work back home, so to speak.
At his leisure he act as a vigilante-assasin and dispatches.. er.. murders criminals he thinks have escaped the legal system too easily. That is child abusers, other serial killers and their ilk.
Being a professional forensic examiner, he knows how CSI (crime scene investigation) works, and thus can avoid being caught. His methods of murder are nothing short of genious. In most cases he sedates his prey with a anaesthetic shot to neck. He then drags them to a special room all covered in plastic sheets. Before killing his subjects, he takes a blood sample as a trophy. After dismembering the bodies for easier transport, he dumps them in the ocean.
Season two ended couple of weeks ago. We are very anxiously awaiting for the third season of his antisocial adventures..
