I hate zombies.
I mean, I REALLY hate zombies.
I think I could manage just about any other supernatural infestation. vampire, werewolf, swamp thing... you name it. no biggie.
but zombies? no, I would freak out and eventually get bitten.
...also can't stand ghosts if they are like the ones in Silent Hill and they are rip-offs of zombies, swarming you and killing you with their touch.
