I like slow, But its because thats how Zombies were originally viewed (NOTLD). The fast Zombie was added to give directors more "JUMP OUT AND SAY BOO" Scenes in a movie. So really when you get down to it fast Zombies are a ploy, not to make the movie scarier as a whole, but rather to give the movie a higher number of scarier moments. I did enjoy the new Dawn and 28 days Later, however niether comes close to the experience of the the first time I viewed the original Dawn.
