The first five minutes really sets the tone..
The first thing you see is a heavily edited quote by Victor Hugo from Les Miserables. Religious references removed, but also leaves out the rest of the quote in which the character is justifying fighting and lying down one's life in order to reach the ideal world. Kind of ironic for an anti-war film. Then we see a cow being led into the thingy with a cattle prod...anyone in the cattle industry knows this is normal. Now, let's fast forward a few more minutes. We see some lions sitting in the plains. Pretty. What you DON'T see are those same lions ripping apart a screaming baby zebra or two males gutting each other over a female. I think I'd rather be the steer going the quick way.
But, really. In a movie talking about how bad humans are...and putting animals in such a light as the 'innocent ones'. Ok, so, wait. Death, killing, violence...pretty much everything humans do is present in the animal world too. Just on a different scale. Why is this being glossed over? It's ok for a hyena to eat a screaming antelope alive, but a human can't do a steer in much quicker for food? Or is the director going to start a movement to turn every carnivore on earth vegan and the joys of 'sharing the ladies' for all dominant male animals?
