From the website overview:
"AFRICAN AMERICAN LIVES 2 again journeys deep into ancestry of an all-new group of remarkable individuals, offering an in-depth look at the African-American experience and race relations throughout U.S. history. Harvard professor Henry Louis Gates, Jr. returns as series host, guiding genealogical investigations down through the 20th century, Reconstruction, slavery and early U.S. history, and presenting cutting-edge genetic analysis that locates participants' ancestors in Africa, Europe and America. Joining Professor Gates in the new broadcast are poet Maya Angelou, author Bliss Broyard, actor Don Cheadle, actor Morgan Freeman, theologian Peter Gomes, publisher Linda Johnson Rice, athlete Jackie Joyner-Kersee, radio personality Tom Joyner, comedian Chris Rock, music legend Tina Turner, and college administrator Kathleen Henderson, who was selected from more than 2,000 applicants to have her family history researched and DNA tested alongside the series' well-known guests."
For me this series does an excellent job of laying out the legacy of the dehumanaizing effects of slavery on our country as a whole for all races. The effects are still being felt today although we don't always make the link. Watching this series helps make the link as well as helping me to better understand the feelings I have about race issues.
