I think this show was excellent and provided plenty of experts in the field from basic beer bloggers/writers, historians, to scientists , the producers made the show "for the standard idiot to understand" but most of it was solid stuff. Dr. Gregg Smith, Dr. Pat McGovern and Moreen Ogle are no slackers , yes there are assumptions as to the progressions of how people acted and thought about beer, but I wager 90% of what they presented was fact, the human condition is repeated throughout history without a doubt, look what we are doing today, yes, technology is advanced , but the human spirit almost unchanged in thousands of years.
