I'll have to think about that. Believe me, I don't fall into the strict thinking of what-ifs about zombies. Fast or slow. That kind of thing. I simply like to be entertained. The resident evil movies do that for me. George Romero's first flick did not. 28 days/weeks did (rage/zombie = same thing). Cemetary Man did. Dead Alive did. And so many more did not. Good question. I'll be back.
