Firstly, If you are looking for an all action, non-stop thriller then look elsewhere because this probably isn't the film for you. However, this is an informative and extremely interesting depiction of the man behind the myth.
The film is beautifully shot, yes there are long parts of this film which involve little action. However, if you are interested in the political background and moral background of Ernesto 'Che' Guevara then you should watch this. The action is simplistic and rough which probably best describes the rebels of the july 26 movement.
Overall, if you are looking for an all out action film look elsewhere because this film is for those with some outline of the history and are interested in the political back drop of the film. 5/5
