As far as "zombie canon" goes, I've an admittedly small nit to pick. Namely, I'm tired of the "reasonable explanations" for zombies and vampires. I wish Left4Dead had -true- zombies, not "infected". It's like, "oh, no, they can't be undead, that's just too unrealistic!". Puh-leze. "Wait, they're infected instead, yay, that's so much more believable, thus fun!". I disagree. Undead a hell of a lot more fun, and scary, than infected people. For me, at least.
Waiting and hoping for the day when media and games once again feature the real zombies . . .and all the emo anne rice-esque vampires die a quick and horrible death.
