I like this film because of it's self reflective nature and it's pretty much a thesis film on the current state of horror films.
This film itself is not a horror film. It breaks down like this.
The kids in the cabin are the films we're used to seeing.
The guys in the control room are the film makers that make said film.
The gods are the "Watchers" or really, us the audience, and we demand to be satisfied.
And the Zombies. that was a clear choice in my eyes as they are making fun of the current craze of zombie movies and their popularity and the fact they made them dumb red neck hick zombies is a pretty clear *** they think the zombies need to go away and they have just become a dead horse the industry will not stop beating.
The film makers have to make the kids dumb to satisfy our thirst for blood and carnage. If we the people don't get that we walk of the film feeling cheated, much like the gods do at the end of this film and rage against those that did not satisfy their thirst for blood. This film is designed to anger those that don't care to watch a film that is a thesis on horror films and made to rewards those that want to watch what these film makers think of the film makers that make "horror" films. Love it or hate it, it's a cleaver little film. I may not watch it again but I really like this approach to the film and thought it was worth a watch.
