I'm a fan of zombie movies. The whole survival against all odds thing and my general enjoyment of horrors/comedies leads me towards both sides of the spectrum with zombie films.

But I digress. In zombie movies, you have two types of zombies.
THE SLOW ZOMBIE
these are slow re-animated living dead. freaky shiet.
THE FAST ZOMBIE
these run/sprint and devour. They tend to shamble about when there isn't fresh meat on the table, but get up to speed fast.

Since most zombie films show the zombies as devouring corpses because they're around instead of for sustenance, I think the slow zombie is more plausible. Sure, the zombie could be fast at the beginning. but once rigor mortis starts to set in, they should be struggling to move, and eventually they shouldn't be able to move at all.

what are your views?
