Though I am relieved to learn that the reference to "separate but equal" wasn't an anachronism after all - it was overturned in the 1950's, but had been around since at least 1896 in Plessy v. Ferguson. So at least I was wrong about that nit (which I wasn't sure enough about to say out loud after the movie, so at least I get half credit about holding back... right? ;-)
Anyway, by the end of the movie it felt a little like they went to Harvard and were handed the debate, "Resolved: the sky is blue. Wiley College will argue the affirmative." Also, the Harvard men made wretchedly bad arguments. Even for a losing proposition they could have fought back better.
But those are minor nitpicks, really. It was still an inspirational movie, and the off-the-podium action was extremely engaging, with what seemed to be an authentic feel of the fear existed in the south the 1930s for them.
It was a weekend for emotionally striking movies, actually; I'll have to talk about I am Legend on another occasion.
