If you have Showtime and a willingness to take a long look into moral grey areas to the point of finding yourself looking back, check it out. I almost got Showtime just to have access to this, but I decided to wait for the DVD and what's probably going to be a host of exceptionally curious extras.

The premise, if you haven't seen the Jeff Lindsay novels: Dexter Morgan, second-generation cop along with his sister, works for the Miami PD as a forsenics expert specializing in blood splatter analysis. That's the day job. At night, he puts all those detective skills to use by going out, finding criminals on his own -- specializing in murderers, pedophiles, and other such specimens -- and murdering them. Basically, Dexter is a serial killer who only goes after other serial killers. He has morals, but they're artificially imposed. He has emotions, but they're faked. And he has a wicked sense of humor for a man who can't find anything funny. Some people just deserve to die. Dexter kills them. End of moral conflict.

Maybe.

Try it. You might like it. (The series, that is. Leave anything else up to the professionals. )
