Have you seen the movie "Peaceable Kingdom" yet? If not, it's worth watching! I showed it to a group of people yesterday, seeing it for the first time myself, and I thought it was good. The group of people also liked the movie. It has some ups and downs and it tugs at your heart, but as soon as you are ready to burst into tears it brings you back up and shows you something really sweet.
"Peaceable Kingdom" is a movie for people to see to learn about the connection that animals have to each other (such as the mother/baby relationship), as well as how people can come to change. They interview people at a sanctuary and those who used to raise animals for meat and how they made a transformation.
