I liked this movie because it is different than other horror movies out there. It does something completely different than what has been done already in other movies and for that I take my hat off. It's a body horror-movie, emphasis on horror, so don't expect some intricate, convoluted story here. If you watch this movie, or any horror movie with hih expectations you will be bored and disappointed. But just because it's not some complex story does not mean it won't trip you out with its entirely different plot, which is where the horror (fear) comes in: the unknown. So lower your expectations, watch it, enjoy. That's it.
All indie horror films, in my experience, are the best. They try harder, setting the tone in the atmosphere, environment, instead of CG affects.
