The problem with zombies is that while technically scary in any modern zombie apocalypse there's so many damned guns just laying around that any survivors can easily kill them. This is probably highlighted in Zombieland in that while a more or less serious movie they really made light of the zombie killing part.
So if a movie wants to make zombies scary again maybe they could try a different time period? The more primitive the survivors weapons, the more deadly the shambling hoardes becomes.
