there is plenty of books where zombies could die of bleeding
all the fuss on zombie lore here on this forum always made me laugh a little, i read, watch, play, eat and breathe zombies since a whas a kid, too many moon ago
sometimes they are dead, sometimes they are alive, sometimes they can die a change again when they die
sometimes the only thing stopping them is a trauma to the head, sometimes they can bleed or die from massive trauma
sometimes they can only walk, sometimes they run, sometimes there are different kind of zombies in the same book (movie, game or other media)
sometimes they are dumb, sometimes they have a collective mind, sometimes there are some leader that command the grunt
the only thing that all of them have in common is the name, but saying that zombies HAD to have some characteristic is nonsense
romero made an excellent movie, but even him reinvented the zed for his purpose, why TFP can't do the same?
