I'm not really sure which is more geeky; the fact that there is fast vs. slow zombie argument, the fact that I am going to post my thoughts on it all, or the fact that you are actually going to sit there in front of your computer and read what I am about to post. You are here to begin with, so you have already embraced your geekiness, let's continue on full speed ahead. Back to the matter at hand...
Fast vs Slow
Proponents of the "fast" zombie, as seen in, say, "Dawn Of The Dead (2004)", think that they are much more terrifying, in that there is no getting way from them, short of being a track star. Fast zombies also open the door for a broader interpretation of the genre. The "rage" zombies from the 28 Days franchise are a good example. They are zombies in every aspect, other than they are not "undead". No matter where you stand, you have to admit the idea of being chased down and being eaten, by anything, is an unsettling thought. Especially true if you were a slow poke, like me, as a kid. I wasn't fat, I was "husky"!
I fall in the middle. I think that both types fit perfectly into the genre, and can in fact co-exist; especially in zombie games. From a physiological approach, my stand point makes perfect sense...well okay as much sense as can be had in this discussion. Think about what happens to the human body when we die. Immediately, the body starts to decompose. Within hours, rigor mortis sets in, making the body stiff. hours, sometimes days after that rigor goes away, and the joints are again easily movable. If we apply what we know about horror zombies to the process, we see stages in the life (death?) cycle of a zombie.
If you've stuck with me thus far, I'm gonna leave you hanging, until the next post in a few days. In it, I'll lay out the "logic" behind my stance, and walk you through the pathology of the zombie cycle in the world that Lazarus exists in.
