I responded differently than any of the other reviews I've read so far. I think the movie is making the point viscerally that humans--even sympathetic humans--wrongly treat animals as their property, to own, to kill, to eat, and in this film to bring into their family at will. If animals develop human intelligence and skills (such as the ability to use a gun), they can fight back. The ending was a pretty awesome surprise. This is a nature lover's and a vegan's film.
