In almost every movie ever made, at some point, a character will consume animal products: a cheeseburger, a steak, a tuna sandwich, an omelet, a slice of pizza, a milk shake...whatever. Often, the script will even have characters specifically voice their love for such fare.
In the reviews of these films, of course, you will see no mention of this. No film reviewer would ever condemn a movie simply because the protagonist ate and enjoyed, say, a grilled cheese sandwich.
However, if you were to release a movie that directly addressed the standard American diet and animal consumption, every wiseass writer would be poised and ready to get glib and trivialize the message. It's all part of the subtle, daily conditioning we endure. If you don't believe me, check out some of the headlines for "Fast Food Nation" reviews:
