Query: Full of Vital Protein !!

This is a rare cult item - I've been looking for a copy for a long time. It's a serious look at cannibalism in films and culture, and also in history and true crime. Repeat: a SERIOUS look. Even though it looks like a gorefest from the picture on the cover, it's not - it's a wide-ranging study (maybe a little beyond some of the people who gave it a low rating). It's NOT a PhD dissertation, as somebody says here, but an in-depth look at something disturbing. The bottom line: don't buy it unless you can handle some deep thoughts, or you'll be disappointed - like some of these reviewers seem to have been.
