Zombies never made as much sense to me as revenants do. I can buy the idea of a spirit taking control of its old body and piloting it with the, ah, detachment of the grave more than I can really believe in a shambling zombie with a hunger for brains and warm flesh. The latter just seems to require more steps, I guess.
Anyway.
I hate that we conflate zombies and ghouls now. I blame Romero for this.
But revenants are by far more interesting!
