Romero may be bringing more of that theory "Intelligent" Zombie, as he did with Bub (Day of the Dead) and Big Daddy (Land of the Dead), The "Nun" Zombie in "Dawn" (shes outside of JC Penny's). After all Day was not what Romero originally had in mind, it was a more "modernized" script to also deal with the budget of the film. "Day" was to take place on a remote Island where Zombies were being trained to be an army. Take a look here:http://www.homepageofthedead.com/films/day/script. ...Romero likes to preserve some of our culture in his Zombie movies. Aka the Mall craze in the 70's became the focal point of "Dawn". Nuclear Bunkers for "Day" in the 80s for "Day". And the Homeless issues that are occurring today for "Land".And it always seems like Romeo has a "okay that was nice... let me show you how to make a real zombie flick" when a handful of Zombie Flicks come out within a few years of each other (Zombieland, Dawn Of The Dead Remake, etc). This is "his" way for saying "this is my version of a Zombie flick"...that's my .02
