...this is the way people talk. How you could have a story set where and when this story is set, among these characters and not have profanity is something I don't see how it could work. Keep in mind, not all the characters do curse very much, if at all. But some do, and that accurately reflects life.
Likewise, the story is about--among other things--sex. That is a perfectly valid thing for stories to be about.
Oh, I know that. I was merely making an observation that there's considerably more profanity in TrueBlood than in the books, as well as that the sex in TB seemed more explicit for a TV show than the sex in the novels was for books. And when I complained about the hick accents that some of the actors were putting on, it was primarily because, at one section in the first novel, Harris mentions that a character (who, despite being a somewhat minor character, will likely be the hardest to cast; I refuse to spoil the hilarious reason why) speaks "with a thick Southern accent" - which, at least to me, implies that the other characters' accents are light to moderate.
There are a lot of differences, though. Bill is far more diplomatic than Barnabas, and seems more comfortable with his vampire status. He isn't nearly as aristocratic, nor seemingly as vain. Not a ring or over-elaborate cane in sight! If anything his wardrobe is very ordinary. Plus he doesn't seem as obsessed with the past, the way Barnabas was forever dwelling on what had been (often at the expense of what was or could be).
Yes, those large differences in their personalities are why I don't really consider Barnabas and Bill to be similar people. There are some big parallels in their situations, and a few small ones in their appearances and personalities, but I don't see them as being similar people.
Anyway, I am looking forward to seeing who they cast in that role that I mentioned earlier; like I said, they either need to cast it flawlessly or skip the character altogether, and the latter would be terribly unfortunate.
