Vampires Jesus and Zombies!!

So I was wondering why are vampires so scared of the cross. I mean You've never seen a vampire scared of an Ankh or a crescent moon with a star or even an inverted cross(then again that would be funny) So why the cross? Do they fear Jesus? So all these years millions of people who flock to see a vampire movie in which the vampire at some point in the movie faces a cross he is acknowledging the existence of Jesus Christ? I mean why fear Jesus( and I mean that rhetorically) Jesus was the first to rise from the dead and LIVED! He (although some may argue this point) was not (technically) a zombie. Yes I know many believe that Jesus was a zombie(as offensive that may be to some of you) Jesus is the undead LIVING where Vampires(or Dracula,Vlad knock yourself out) is the undead dead..wouldn't they want to be risen to the living as well.. instead of eating brains(for those with the zombie thoughts) or sucking blood to eating dinner with a family member or being able to show that there is life after death. Why fear what can give you life and breath again..heck you get to roam freely whenever you want day or night(..and eat garlic) but past that small niche, Being alive. It just tickled me the idea that these movies where slightly in s small way Acknowledging and preaching the existence of Christ. Lets say that its just a cross that its a symbol of an "old"religion an amulet of safety even then they come to some point that at the cross(at the foot of the cross) there is safety in Him.. there is safety in the cross.. for there our sins where forgiven.. we're safe from the evil ones clutches. From that undead The cross brings us safety.
