The first two episodes were somewhat innaccurate historically, and very superficial. I did win a bet with myself on episode One, when Kenny got into the racism angle within the first thirty minutes.
Amen. The Holocaust, racial segregation in the US Military and the forced resettlement of Japanese-Americans are some of the few historical facts today's school-kids (and their parents)might actually know. Why not tell them a few things they don't know instead?
