Depends more on the medium... In games... you can't kill the same slow shuffling zombie forever (except maybe in the best MMO ever )
But the slow shuffling kind are scary. Terrifying. It's the difference between slamming into a pane of glass and slowly pressing on it more and more... never stopping... not for breath or for sleep... just pressing and pressing... You can see a crack start to appear in the corner of the glass and you know it's going to crack, but you don't know when... you start to ready yourself for the inevitable crash of glass and blood, but you have to sleep... and they don't... they'll just keep pressing and pressing...
ANYWAY, also there's the fact that they're an unstoppable wall of death. You can keep shooting hundreds of them a minute, but they'll always be there. Always hungry. Always coming
