So I watched "Lincoln" online Sunday. A very serious movie that has been falsely represented to some degree. It is NOT a biography of Lincoln. It is focused specifically on his efforts to pass the 13th amendment and all the back door dealing that went into it. So it's starts already 4 years into the war.
I was a political science major in college, and studied the politics of this time period. So the movie was of some interest to me. But if you are looking for entertainment, keep going.
