We tend to think of the past as settled. There is nothing we can do to change it. But this is not entirely true. The movie "Coco" shows that we think about the past – the good guys and bad guys, the justice and injustice, the causes and effects – has a profound effect on our perceptions of the present. Our understanding comes to be revised based on new information as it comes to light. In this sense, the past is not settled. It is a living reality.
