I was a little skeptical about “The Vampire Diaries” until I watched this teaser. I thought the CW was just trying to capitalize on the vampire resurgence in the cheesy way that only that network can. But I was wrong. This trailer gave me the same excitement I had when I first saw “True Blood” and read the Twilight series. You can bet we’ll cover “The Vampire Diaries” in the fall once it premieres. Will you watch the show? Or are sick of vampires already?
