The movie isn't a documentary about meat eating being cruel. It simply sticks to the facts about what meat does in your body and health issues that are exacerbated by eating meat. The one that really gets me is the link to cancer. It appears that eating animal based protein is like tossing gasoline on the fire if cancer was the fire. 20% animal protein in the diet caused drastically increased cancer growth whereas 5% animal protein in the diet was VERY low in cancer rate/growth.

It's totally worth watching if only so you can understand how meat ties into your overall health.
