"The books weren't great, but the show really started to go downhill the more they veered from the source material. Like in the books, Sookie pretty much has no interest in Bill past book three. And for most of the remainder of the series, until the last book, it's all about her and Eric. The show forced the Bill/Sookie relationship solely because the actors were a couple in real life.
The only good characters that show created (compared to the books) was Lafayette, Jessica, Godric, the Newlins, and Russell."
