I've watched most of this movie and found it very interesting. It's not like this is like a new thing to me, I know it's going on, but I don't really think about it when I'm eating a steak..... probably will now though.
If you havn't, I would recommend it (except for small children or people with a very weak stomach or people subject to intense bouts of rage due to animal abuse)
