Why are people confused? (spoilers)

So a guy finds plants that have a certain discoloration to them and knows that, if lucky, he can find a complex parasite. He finds them and then uses them on people to get all of their money. This worm, in a way, becomes a part of that person and is then transferred into a pig. The pig and the person are now eternally connected. This cycle has been going on for a while until Kris comes into the mix. She finds another survivor and they slowly try to figure the whole ordeal out. They find the pig farm, she kills the man who was herding the pigs and not allowing them free will. They find the other victims, they take care of the pigs, and they have their life back. We then see the guy from the beginning again and he's looking through all of the plants and can't find the correct discoloration. The cycle is over.

I don't mean to sound rude, but the review on the front page makes it sound like some people didn't even try with this film. What does it all mean? I'm not quite sure. But saying that the film is nothing but a bunch of moments that stick with you but don't stick together really isn't fair. The film tells a clear story.
