Classic slow shuffling zombies or modern fast parkouring zombies

It's a little easier to believe zombies taking over the world when they are fast and aggressive, like in the Dawn of the Dead remake.

A slow zombie outbreak would end like Shaun of the Dead.

I don't particularly like zombie movies, but I guess I Am Legend qualifies. I know some super strong zombie was breaking the glass at the end of the movie. I forget what Will Smith did about it.

Of course slow. The entire horror of a zombie apocalypse is the ever approaching end, the sheer number and vast hopelessness of it all. There is only so long you can run and hide before it overtakes you. That's the dread of zombies, not being chased down by a track star.

I liked the concept of Aaah! Zombies! (2007) where the film was from the zombie's point of view and everyone else was moving super quickly.

Honestly, I think that if the zombies are rising from the grave they should be slow, if they are newly infected then I think they can move quickly or slowly.

Zombies that drive, Uber or take mass transit

You're not going to believe this, but I've never watched anything with zombies in it.

But I'd choose creepy slow-moving zombies. In fiction. If there were such a thing as zombies, I'd choose the same but my reasoning would be totally different ;p
