Unfortunately, this was one of the worst interviews that I have seen Dr. Campbell give. He seemed way off his mark, not sharp, and not convincing. I love the man, but feel this may not be the type of format that is best for him to speak in.

Bill Maher is a long-time vegetarian. I thought Dr. Campbell gave a horrendous interview. He seemed out of it. He didn't understand some of the questions. I was embarrassed watching him.

This was the worst thing I have ever seen. It was actually painful to watch. Dr. Campbell was like an old man that didn't know where he was. He didn't understand even the most basic questions and couldn't even explain the title of the movie, his reason for being there! It was like watching someone you once knew fall victim to severe Alzheimer's Disease. Campbell was clueless and embarrassed himself. He should have deferred this interview to Joel Fuhrman or someone that can talk at the celebrity level. I felt so bad for him...I was crouching in the corner. What a train wreck...poor guy...RETIRE!!!
