Each part of the film tells different stories. The first part deals with the Cuban revolution, while the second part deals with Che’s futile coupe in Bolivia.
I have to say that I enjoyed part one a bit better and I found part two a more low-key and somber film (however, I believe that was partially the goal).
Either way I thought Benico Del Toro was excellent I would recommend seeing at least part one.
Part One: 8/10
Part Two: 7/10
