It's the crushing inevitablity of their numbers, their lack of fatigue, and the complete perfection of willpower which makes them scary.

Fast zombies give no time for the involved character to have any interaction with them. There's no horror or fear, there's just "OHCRAPAZOMBIE*Blamblamblam*OKITSDEADNOWK!".

I can't remember where it is, but Simon Pegg (Shaun of the Dead) wrote a vey good little piece along pretty much those lines.

So yeah, slow, ambling, mal-coordinated zombies. If they have to exist at all.
Shaun of the dead was funny as hell, but raise your hand if you seen Land of the Dead..... If you have seen it you'll know what Im talking about, theirs a scene where the zombies bust through a mall and attack the people inside, the people take off running while the zombies are shuffling, never gonna catch up right? WRONG, next scene all the people are getting torn to shreds, how the hell did creatures that move .2 miles an hour catch up to fully sprinting human beings? Its not scary its funny, in the 1990 remake the zombies are shown to be how weak they really are, the main character basically side steps through them all. I think if I keep running like this that zombies never gonna catch me, let me fall down to give them a fair chance.

The concept of zombies rule though, it plays to the primal fear of being eaten alive, also it may be you love ones doing the eating, I just like my horror movies to have creatures faster than my grandma.
