If you are reserved about buying an American or any other DVD from a country not your own, don’t be. See DVD hacks and search for the make of your DVD recorder and you will see how to make your recorder fit for All areas.
I have only watched the first 3 episodes of this most disturbing DVD with the protagonist, an actor I find awfully difficult to dislike. He was in Six Feet Under too as the gay brother.
Either I have to give this DVD viewing away, because I cannot yet sympathise with the supposed serial killer who works with the police as a forensic blood spatter expert or I keep thinking there is going to be a twist to this as we never hear of any discoveries of bodies that the main character supposedly disposes of.
The review above gives me hope.
