Zombies...?

So, Cabin in the Woods. This is a strange film to me. It doesn't come off as a Zombie film to me. The Zombies don't seem to play a major role in the film. Because the idea is the hero in these stories, but the idea here doesn't seem to be, "If you ignore the superstitious signs, you will be eaten by zombies." The zombies are a transition state, they represent all of the fairytale/supernatural characters that play a bigger role in sacrificing humans. We have yet to finish to the movie, but Gods and sacrificing seem to be at the center of the plot. The Zombies seemed to be chosen as the means of killing the humans because this is supposed to be a scary movie and producers needed a killer that would bring in people to the movies, and zombies have been a consistent and reliable staple of scary movies for a long time. Zombies, all in all, don't seem like a major necessity for the plot, but a way to make this movie more appealing to scary movie goers.
