My preference is very much Romero style, slow, dead risen type zombies.<br/><br/>I don't see as there is too much chance of surviving fast zombies beyond a certain concentration even if they are technically still alive and easier to put down, without already being holed up at the start of the outbreak. Then all you have to do is stay holed up for two months or so and most of the infected will be dead from starvation.<br/><br/>To my mind the Romero movies were good because there wasn't the need for exposition. The situation was what it was, the dead were up and walking around eating folks and that was that. No need to explain further, at least definitively (1). They are slow, yet inexorable, they last for years, so will remain a threat for decades. The films are very much about the pressure cooker of being hunted and under siege on the human character. They are about the characters and their interactions far more than they are about the antagonists stumbling about the place.<br/><br/>They are still a very real, very valid threat as they do not rest, do not feel pain, will never stop.<br/><br/>I will accept the consensus, just stating my preference. *Grins*<br/><br/>1) While most of the Romero zombie films have the characters speculating over what caused the dead to rise and attack the living, its just that speculation. Nobody ever claims their reason is the right one and characters offer different ideas in different films.
