I recently have become addicted to Dexter. The show is on Showtime, so there's some language, but not as much blood as you would think considering the shows subject matter. Dexter, you see, is a sociopathic serial killer... but he only kills murderers. While the ethics and morals of this in the outside world are debatable (not mine however) it's everything else about him and how he lives his life with people that feel and love, which he doesn't, which is the real fascination with the show for me. I would wager that the first episode is PG-13, but I couldn't be sure. His sister in the show has a spectacularly bad mouth, and flaunts it a lot lol. But if you're looking for something different, something really different, try it out.
As for my own sociopath in my book, I've decided to rework the story, while I was telling a story about something I found interesting, the story didn't match the subject matter very well, and it needs to 'click' you know? If it doesn't click for me, its not going to click for everyone else. So, back to the drawing board somewhat.
