"Proof" is a movie about family relationships and also a love story. "Love" is the most fascinating of the many elements of the film, perhaps because it is the least selfish. The emotional performance between Catherine and Hal surpasses the performance of "family affection" in the film. Jacob Benjamin Gyllenhaal and Gwyneth Paltrow played well in this part. But as far as the main theme of the film is concerned, "Proof" does not show the insufficiency. As for Catherine's proving to be a martyr to her father, the film is not convincing
.
"Proof" is a perfect collection. It uses movie language to bring stories about life and sadness. Director John Madden used a brisk and concentrated picture to show the fascinating scene without burying the main structure of the plot
