Interesting to see what the term "Omnivore" actually means, especially in context to what the movie is about. Not really the same thing ... a different kind of "animal"(beast) if you will. But this movie is pretty far out there, not only thematically, but also graphically, so it's not for the faint hearted.
There is also nudity and sexual situations in the movie, but those are not the graphic elements I'm warning you off, it's the violence, but also what you have to "digest" during the "course" of the movie (puns intended), that might make you feel bad. Predictable for the most part, this is an interesting look at the human psyche ... could've been more thorough on some aspects, but as it is, a nice little thriller
