I enjoyed "Fool Me Once" as well. I didn't like "You are What You Eat" because I thought the title was misleading. I thought it was all about the twins eating study, but it was so much about (Wait, I should stop talking now as I don't want to end up writing spoilers...) I skipped through and watched the results of the study.
We started watching "You are what you eat" also. Then they started devoting more time to politicians and political points. Still interesting, but will skim the rest.
