Zombies

My review is for the paperback book that I borrowed from the local library.
Richard Matheson's book I am Legend is about cannibalistic vampires, they aren't zombies, I don't understand why they are always described as zombies since they are cannibalistic vampires.
It's one of my favourite books.

I'm already a fan of Neil Gaiman (I still need to read his books, but I like adaptations based on his books)
I haven't read any books about zombies, but there are classic Gothic tales about people being buried alive, returning after death by Edgar Allan Poe, and other authors that I really like.
The fact that the government could create a real or artificial drug that reanimates necrotic tissue of the dead is disturbing and creepy to me, especially if it was done for just for population control.
