The film opens with probably the most gruesome part of the whole film. A young boy, Dimas, is left alone with his sick mother in a cabin. When they have run out of food and the mother dies - the horrifying inevitability happens. Dimas grows up to be the host of the cannibal clandestine restaurant, with the help of his butcher Matarife. At the first restaurant Marcos goes to, he meets Eva, who offers to help him maneuver through this secret world and with whom he has a bit of a tryst. There is no hint of a backstory for any character other than Dimas, so the movie becomes entirely plot-driven and situational. Which is totally fine with me. But I was so curious about Matarife (though I had to do some research on what his name was because they never said it as far as I could tell) and what his story was and how he hooked up with Dimas, etc. With everyone else you can make inferences about their characters, and you'd probably be right.
The ending is nothing short of delightful. Truth be told, I was expecting a fairly bloody mess as Marcos had to kill his way out of Dimas's home or something, but I was actually quite happy that the filmmakers chose to make the conclusion much more subtle, while still immensely satisfying. It quickly becomes obvious just which direction the conclusion is heading, and it only made me more giddy to find out I was right.
Omnivores is an interesting movie that many people will probably see as boring. To me it had the quirkiness of a Tales from the Crypt episode, where you may not be into it the rest of the episode but the climax makes up for all of it. I thought this movie was a nice, quick, new way to look at and deal with cannibalism and I enjoyed it for the moment.
