Was Debbie the most hated character on this show?

No. I think it was Bill as other members have mentioned but it is worth noting Bill and the actor, Stephen Moyer did have a big fanbase and a lot of his fans were disappointed with what the writers did to his character.

Who???

Most hated was probably Sookie or Bill. And I didn't hate them but I know how many do.

Her and the waitress Sam was with briefly(what was the name?), seemed to be the most hated.

Tara and her mother were pretty awful.

Sam Merlotte - worst mayor ever, guy who doesn't believe in mourning the death of any of his numerous true loves, and avid plaid shirt wearer - is my most hated character.

No, I'm pretty sure the most hated character was Bill

I know I'm a vampire, Snookie.

No, I hated Tara more. Or rather, what they turned Tara's character into.
