I watched this and found it fascinating. Unfortunately, this should be billed as a fairy tale, a political piece of propaganda. Che is represented as a man of the people. He is compassionate, a revolutionary and self-less. This is not at all accurate.
This man was responsible for thousands of deaths of the "people", he supposedly was helping to free. The ordinary person, who wanted a life free from an autocratic governance but all they got for their suffering was death, hunger and even greater poverty. Trading one misery for another in the guise of Fidel.
I used to think this story was accurate after all, I'm an average American who heard about this hero, the Savior of the people of many South American countries and most significantly Cuba. However, over the last 30 something years, I have had the opportunity to speak to many who escaped Cuba, their stories contradict this one! I have heard first hand accounts many decades after the fact, where the individual has had tears in their eyes, literally stopping their account because they were on the verge of weeping. Che was a monster, most likely a sociopath with the power of persuasion than roused people to fight for a cause that would never come to pass.
I am embarrassed of my past belief. I was sold a lie. This film continues to perpetuate it. Do some research, if you know a Cuban, who lived during these times, ask questions. Read some books like Carlos Eire's account as a child in Havana during the 1960's (he doesn't mention Che but he lends his childhood understanding). Information is available, or you could watch a fairy tale, the choice is yours.
