Christians and vampires, can they mix?

Can someone please explain to me why Christians are so enthralled with vampires? Why are we so intrigued with the darkness? Why do we want to entertain it in our minds and before our eyes? Why was their such an outrage about Harry Potter but now those same parents allow their kids to read and watch all the vampire garbage? Where are our standards? Are they liquid? Able to move freely as we so choose? Or are we what we really say we are, believers of The Word - I'm pretty sure vampires don't fall in the category of whatever is true, noble, just, pure, lovely, of good report. It really bothers me that we are so easily sucked into the enemies games and call it entertainment.
