Cabin in the Woods

Cabin in the Woods was not a movie that one would expect to watch just by reading the title. This movie surprised me with it's super-supernatural elements and being that were introduced to us as the audience. The movie portrayed supernatural elements, that originally were thought to possess their own spheres, and mashed them into a pot all at one time. With this, us as the audience, become later confused as to the nature of the storyline. In the beginning, there are two narratives that follow in the same footsteps. There is one narrative that is in control of all the actions and the other that have somewhat control, but are put into the position where they feel helpless. I feel that this movie, in a sense, broke down the fourth wall when the college student realized they actually had the power to control the outcome of the world's destiny. And I think it's and interesting perspective, especially given that this movie is intended to be a horror film (where the victims feel utterly helpless and have predestined end). I wonder what would have happened if they knew before that they were in control they whole time to the supernatural being they were being sacrificed to?
