Without disclosing anything in particular, it just came to mind while observing the very first couple of minutes of the fourth-season premiere of True Blood, which airs Sunday, June 26 on HBO. There was clearly an occasion when True Blood was about vampires. However progressively, the creators of the show seem to be thinking of something lacking with the series. So now, to go in addition to vampires, you will find fairies as well as werewolves and shape-shifters.
