Cabin in the Woods

Let me just start off by saying, I really love this movie so far! and the reasons why are as followed:
Cabin in the Woods seems like it would be like any other traditional scary movie that's set in a cabin in the middle of no where; something absurd is going to happen, either supernatural or psycho pathological and everyone who went on the trip who are usually young and beautiful will die horrible deaths. In this movie; however, they not only have the supernatural aspect of it with the redneck zombies breaching from the ground and killing everyone, but they also have a very sickening plot alongside it: people are controlling these monsters and setting a stage for these young people to be slaughtered. It is unclear why they are doing this, but it is definitely set up with a purpose to kill all of them and to not let them escape. Everything is recorded, stimulated, and programmed to run in a specific way. It is unclear who the audience is that these governmental type officials are doing these acts for, it has not been explained yet. However, there are hints to Egyptian elements in the latter part of the movie. Cabin in the Woods is supernatural yet can still be explained and rationalized which makes it even more thrilling and illusive. In this movie, these zombies are mindless and killing these people, but the true monster are the people running the system.
