Proof - 6

This film is less about math and more about family. Catherine, played by Gwyneth Paltrow, struggles to understand her father's life in the days following his death. He was a brilliant mathematician who later in life went crazy. Not only does she have to deal with her sister, who wants her to move to New York with her, but one of her father's former students wants to investigate her father's later work to find a math break through. In this process they all learn things about the value of family, the pain caused, and the trust needed to sustain them. The acting is good and the story, while not chronological, works to weave together the events that keep if from being cheesy and sentimental.
