The standard for zombies only really exists in thoughtless mass-consumed material. Zombies have many variations and rules. Zombies in general shouldn't be just about 'the dead kill people', they can be a great tool used to create a story, why not use that tool. That being said I still enjoy dumb zombie entertainment.
For me, I prefer the old Romero style, slow, eat people, barely coherent, destroy the brain. Night of the Living Dead, Dawn of the Dead. Video game wise oldschool Resident Evil.
But zombies come in different flavors from the styles of
Left 4 Dead
the remake of Dawn of the Dead
Return of the Living Dead
George RR Martin's Meathouse Man
Sankarea
Tech Zombies
the remake of Day of the Dead
Plants vs Zombies
Zombies with Guns
Lollipop Chainsaw
Suasan Palwick's Beautiful Stuff
Herbert West-Reanimator
to name a few. They exist you just have to find them.
