Glad These Zombies not Running...
as Future Zombies learned how to do.
Kind of like how the original Frankenstein creatures and Mummy creeped along, but they caught people. Dumb people!!!
The only movie where I actually bought into the zombies being able to run was the 28 Days/Weeks Later movies. Mostly because they weren't actually zombies, they were living people.
The idea of the dead coming back to life already requires suspension of disbelief, but seeing a rotting, shambling corpse sprinting like a triathlete runner is beyond absurd. Zombies are supposed to be brain dead, slow, and dumb. It's their numbers that create the danger.
