I saw this film at the Brussels fantastic film festival 2013 (BIFFF). It was announced as a Horror movie, but you are mistaken if you want something sinister. Everything happens in broad daylight. On the other hand, there was sufficient blood&gore to let it fall under the Horror category. Still, I found it more of a Comedy rather than anything else.
The plot elements were cleverly employed, like the use of human bodies (from travel accidents, at first) to "improve" the fertilizer that the two brothers produce. They have a lot of success with it, and demand is rising. Due to the latter, any human body that is found along the road that does not move, is carried away without proper medical review. That is where the story starts, soon involving three hitch hikers who pose an imminent danger to their secret operations. They thus become potential ingredients for their fertilizer production process. Though the cutting up of bodies is only shown once and not very directly, you can expect an abundance of blood sprayed around, tainting most of the bystanders who have every reason to assume they are next in line. Those movie lovers fainting on the sight of blood, are better off when they avoid this one.
The real secret ingredient of this film, however, is the humor that is incorporated all over the story, and works very well in hiding there is no real story to tell. Things happen in a logical sequence, though, but different from what we expected upfront. That is precisely the most important feature of this film. It is a Comedy rather than a Horror movie, is my conclusion, with the blood&gore only as binding element.
All in all, I found this Horror very enjoyable. I usually try to steer clear of blood&gore movies, but this time it is not the central theme that binds the scenes, unlike some other movies with no recognizable story line other than providing for reasons to miserably end other people's lives. In other words, the blood&gore is more entourage here than anything else. The relationship between the two fertilizer making brothers is much more important, as is the hasty and uncoordinated way they try to cover their tracks when the darker side of their business might be exposed. Along the line we witness various ways in which the younger brother tries to show initiative, in an attempt to outsmart his brother who obviously has the lead in everything. And the people who are so unlucky to get involved in their "factory", mostly fail to survive the encounter with all limbs intact, or even to escape alive for that matter. Hilarious scenes throughout, in spite of the darker aspects of the plot.
