I loved the story line on Season 4! This is a must for any fan of the show (I already have seasons 1-3).
This season, Sookie, Eric, Bill & the rest of the residents of Bon Temps have to deal with Witches - Eric ends up with amnesia & there's a love triangle with Eric, Sookie & Bill. The Witches cause all kinds of problems with their magic. There's Fairies, Vampires, Werewolves, Werepanthers, Ghosts, Witches, and even a very strange baby! For fans of the books, it's a little different but still a must watch season for all fans.
