Well like a root canal, its finally over. I in fact did not watch it but my wife was hooked...so the synopsis is
Final episode, white people do more bad things to native americans while a few whites wring their hands and denounce what is going on and are powerless to stop it...Roll credits.
So my understanding is that Speilberg has a movie about Abe Lincoln in the works with Liem Neeson playing lincoln.....
