I agree there is a variety of types of undead ghouls from a variety of socio-cultural contexts… but we’re specifically talking about popular culture zombies, which have clearly taken on a number of forms, some distinct, some more in line the three categories of the undead. I think what you’re getting at is you have a general problem with films/shows/comics, what have you, which employ the term outside of the specific context of #1. But as you can see by the list from wikipedia I posted, there are plenty of films which use zombies, which are taken from the post-Romero understanding of zombies, as the living dead ghouls, who like to eat brains (llater installments of the series, as others have pointed out in the thread).
I do agree that language matters, but it also evolves - it’s not a static thing, nor has it ever been. You could make the argument that any horror films/books/shows, etc not set in Haiti, West Africa, or in Yoruban influenced American communities shouldn’t use the word at all, which seemed to be a very different argument from what you were making above (you’ve given me more details on your view of it here, so I appreciate that).
But given the general plasticity that the term has taken on in popular culture over this past century or so, this show still fits within the wider definition of a zombie as we understand it through popular culture, I’d argue. You’re right that it’s different from original definition. Other ghouls and monsters have also transformed through mass media. The notion of a vampire has very much changed, starting with the publication of Dracula back in the Victoria era. Does that make, the vampires in Buffy, for example, any less vampires because they don’t conform to pre-Dracula conceptualizations of vampires (which weren’t sexy, etc).
Or what about changes between the understand of zombies from West Africa pre-slave trade to the post-slave trade new world? How much do you think that the cosmological views of West Africans changed over time as they were assimilated into the brutal world of the Atlantic slave trade and then trying to figure out how to live in a world of white supremacy after the end of slavery?
I know you disagree with me, but I hope you’re not comparing me to Dubya!
Also, do you have a specific interesting in horror and these sorts of mythologies? You seem to have invested a fair amount of thought into this…
