In all honesty this is not the first zombie flick to be told from the zeds perspective....
"Dead men dont die" was told entirely from the perspective of a zombified business man.
"land of the dead" one could argue that the story is told from the lead zombies perspective centered around his evolution into something more than a zombie.
"Zombie Honeymoon" was told, again entirely from a persons point of view as they became a zombie.
Andrew Parkinson's "i, zombie"
"Dead and Breakfast"
"interview with a zombie"
"my wife is a zombie"
"i was a teenage zombie"
"i was a zombie for the FBI"
"I walked with a zombie"
Sorry but the list does go on and on for this idea.
Kudos to them for getting to cannes and all but for backyard zombie epics this certainly is one of the better, Plaga zombie! i dont really need to say more than that
