Don't waste your time with other Vampire shows. True blood is a show for the true vampire lover. This is not you little dauther's vampire story. Oh noo! This is not the story of eturnal puberty, prom dates, and after school fights. If that's what you want, then I suggest The vampire Diaries. But when you grow up, True Blood will keep you wanting more. The first two season have left me with a major blood lust.
The BBC has also but out one season of Being Human. A story of three roomates who just so happen to be a Ghost, a Warewolf, and yes a Vampire. You might think this to be comedic and it often is, but thier dark super naturial problems are nothig to laugh at.
