The entire premise of the show is based on the idea that synthetic blood can be manufactured, so vampires can live out in the open without threat to human life, ( I know, I know... very sci-fi... but come on, it IS about vampires after all). The vampires struggle to have the same civil rights as humans, and to fit in with human society without fear of persecution. Some vampires are "good", and some are not happy with the change in status and are still killing whom they please. There is also a whole sub-culture of sex-crazed vampire groupies who get paid to let vampires bite them.
However, with the good must also come the bad... there is just TOO much sex in this show. I didn't really need to see so much of the lovely Anna Paquin. I expected as much with an HBO series, as sex is what sells these days, but it borders on pornography. I've been reading reviews of season 2 and it appears that viewers are in for even more graphic sex scenes than were present in season 1. I wish they would tone it down a little, but who am I to judge?
Each episode ends with an incredible teaser that adds drama and keeps me watching. It's not nearly as addictive as Twilight, but it will keep me going until the next movie comes out in November.
Have you seen the show?
