So, now that I'm watching the show, I'm gonna join in the discussions from two years ago.
All the episodes up until now have been character introductions as far as I can tell. It looks like the writers have a good bit of arc they're trying to set up for a long run.
Jason's character doesn't seem to be so useless. He seems like he's going to be the good-intentioned southern boy who goes the wrong way. Eventually, unless the writers do something interesting, his character will become totally superfluous and suck balls. Right now he's only comic relief from the forbidden bad-boy love affair between Sookie and Bill.
Bill's bad side was interesting to see. Stephen Moyer's acting, at first, was a bit over-dramatic and strained, trying to play a caricature of a vampire. Now, it looks like he's trying to be the "man of little words" as he's relying heavily on facial expressions and body language to act instead of using dialogue. We'll see where it goes. Character is a bit of Rice's romantic-and-nostalgic-for-times-since-gone vamps.
Sookie... grew-up-too-fast-because-she-had-super-telepathy-powers-self-reliant-girl-power-powder-puff-southern-belle. Paquin's performance is a bit dry, if not reserved.
Sam's a serial killer who likes to kill women in love with vamps. Please tell me I'm wrong and that the writers didn't make his character that transparently cliche.
Overall, lots of room for improvement, but I'm going to give the rest of the season the benefit of the doubt before watching others.
