Zombie beavers?!  Why?  That being said, I guess a movie that features zombified beavers shouldn’t be too much of a surprise to me, yet it is.  Mostly, I don’t understand the choice of animal.  I would think that zombie house cats would actually be more interesting.  They’re certainly more common than beavers in most places, and they’re already sort of scary.  Couple this ubiquity with their superiority complex towards two-legged animals, and they would make perfect zombies.
