There arguably isn't a more remembered President of the United States than Abraham Lincoln (Daniel Day-Lewis). The story of how he overcame political and personal obstacles to bring a war-torn country back together, while simultaneously ratifying the Constitution to abolish slavery, is told masterfully in Lincoln.
President Lincoln was a shrewd politician who knew just what buttons to push to sway members of Congress to vote his way, but at home he was a less than doting husband and father, often times ignoring the needs of his sons to work, and once threatening to have his wife Mary (Sally Fields) committed to a mental ward.
Important men in history are often only remembered for their accomplishments, but rarely the path they took to get there. Spielberg and Day-Lewis plotted that path for us very well.
