I saw the film, both Part One and Two. I have read a lot about Che's capture, and that is what I wanted to see the most (how Hollywood portrayed it).
Not surprisingly, I was disappointed. The film ignored Guevara's hardline Communist beliefs and instead made him look like a liberator. He justifies his actions throughout the film, especially in Bolivia, as helping the peasants. He asks, "Have you seen how you're peasants are living? Have you seen the infant mortality rate?" But his wanting to spread Communism through Latin America was never mentioned.
What I did like was a scene where the Bolivian president is having a meeting with a couple Americans about Guevara being in the country, and they make a direct reference to SF, saying "we have soldiers that can train your men in guerilla warfare, we did it in Vietnam." They also have a scene with SF soldiers training Bolivian commandos, who in the end kill Guevara after they capture him. How his capture unfolded in the movie is not how it really happened, according to history. But its Hollywood.
