D9 is sci-fi. The 28 X Later series didn't have traditional undead zombies. They were zombies nonetheless: mindless, infected humans, no sense of self-preservation, and a need to feed on human flesh. Return of the Living Dead didn't have traditional zombies, either. They could carry a conversation. Romero's zombies were really the only true zombies. We won't discuss Bub from Day of the Dead.
Here's a question. What category do these films fall into: The Birds, Psycho (original), and Death Proof? Suspense, Horror, Sci-Fi?
More signs that recent Horror films are aimed at women: Twilight. I rest my case.
My girlfriend is very adamant about the fact that if we watch a horror film, I have to make sure to go to bed at the same time as her.
