I won't lie. I hate them with a passion.
Nothing I will say here hasn't probably been said before in the thread, but I'll reinforce those statements nonetheless.
Slow moving zombies. They are creepy, resilient and they WILL get you. That's the whole point of them, and the horrific, terrible truth of it. You can build a supreme fortress of admantinium alloys and have a solar powered super granary that sprouts food forever. It won't matter. Eventually, one of them will come shambling about, spot your little piece of heaven, open it's mouth and moan. If you don't dispose of it, more will come. And more. And more. Eventually, when you realise that they're a problem, there will be enough for them to climb over the corpses of their 'fellows', and get over your indestructible wall.
Even if you DO manage to stay quiet and kill all stragglers, would you be able to live on in a world where zombies are a constant, never ending threat? Every new corpse needs to be burned. You will always be watching over your shoulder. And make note, no man is perfect. You WILL mess up, eventually. Maybe not now, maybe not in five, ten years. But mess up you will, and they will get you.
That's why I love them. So inescapable. As someone said earlier, very chutulu-esque. The fear of death, and the fear of finality.
The new running zombies however. Yes, they make me crap my pants, but they are a very in-your-face kind of monster. They run up and scare you, but, also as stated before, they are generally weak as fuck. Poke them with a stick and they transform into a pile of gore. They have no lasting threat to them. Get a big enough army, or enough firepower and entrenchment, and you're all set. They are a problem you can overcome, and I won't have zombies that can be defeated once and for all. They are not scary over time. Sure, it might not matter, they might get everyone in the first wave and leave the planet humanless, but then what? They will deteriorate and dissipate, and life will eventually return.
That's my view of it.
