What do you do with a show that you want to like but has major problems, most notably that you aren't really interested in the main characters? It's unfortunate, but I have almost no interest in Sookie and Bill except that they are the price we pay to have Eric, Pam, Jessica and Lafayette on the screen.
I also thought that seasons 1 and 2 flirted with too many storylines but season 3 is ri-donk-u-lus. I've said it before and I'll say it again because I think it bears repeating: I wish it was The Eric and Pam Show featuring Lafayette and introducing Baby Jessica with special appearances by Alcide and Jesus.
For the record, a friend of mine does a much more coherent review and expression of her thoughts here.
