In my opinion it's impossible to rate films on a single scale since their goals and methods vary so much, so this is a 7/10 for what it is: an odd experimental indie film.
The basic concept is good. A dialogueless movie showing the mistreatment of animals with the roles reversed. It intercuts between different groups of humans serving as analogues for different animals.
Unfortunately, I feel like some fall flat. People as cattle has been done before and this doesn't do much unique beyond a few especially effective scenes. The dog fighting segment was much better executed until the stories intertwine, breaking the analogy. Dogs and cattle are both often mistreated, but not in the same ways. I think it would have been better as a collection of short films.
The cinematography is excellent though, with bleakly beautiful outdoor shots, grimy industrial indoor shots, and a camera keeping the animal people just far enough away or out of focus to avoid making it too obvious they're just people with costume heads and gloves.
I'd recommend checking it out as long as you know what you're getting into. This is more arthouse than slasher flick.
