5.
A category of the horror movie genre that is defined by its common characteristic of having a minor plot and focusing on the killing and gore in the movie.
Typically it has been portrayed as one maniac killing a group of helpless teenagers, but in recent movies, it has started to be redefined such as in Freddy vs. Jason where the maniacs try to kill each other or as the re-release of Dawn of the Dead were there are many enemies, but the backbone of the movie is in its graphic scenes between the zombies and the surviving humans.
