Twi-screenwriter Melissa Rosenberg says there's absolutely no doubt the third flick in the vampire franchise is taking a darker turn.And she credits the storyline and director David Slade for that...
"David has a darker sensibility, so it clicks," Rosenberg said. "The story has a slightly darker tone. I mean, it goes into a full-out battle, so it is darker in the nature of what it is. David was the perfect director for it."
