Season two is fantastic, and gets more in depth into the vampire's governmental structure, bringing in a gorgeous Queen and complicating things for Eric and Bill. Sookie's love life gets complicated as well- with only fantastic results. The Fellowship of the Sun (an anti-vampire church) comes back in full force, which is a fantastic plot development.
This season is sexier, more intense, and much crazier than the first, in all the best of ways. I would defiitely suggest that any TrueBlood fan own this dvd collection.
