This assumes all zombies were entombed. Not so in most of the modern zombie genre. If we are going with the Romero flesh-eater and it's cousins (which most people are) the first zombies would be those in morgues awaiting embalming, hospital beds, or at home.... As for the blood, while it definitely makes it more gory, I don't think it's too realistic. One of the things they do in embalming is drain the blood. Actually they replace it with embalming fluid. The only blood on a zombie would be from its victims.
You and me both. I'm an old school "back from the grave" type myself. But when it comes to zombies, you gotta ask yourself which kind these days.Zombies 101 Cool!
Thanks for the informative post on Zombies, I didn't realize there were different types. I tend to prefer the rotten just escaped from the grave ones myself.
