This film is stunning and mesmerizing,definitely worth seeing.
However, its message is definitely pro-Fidel, pro-revolution, pro-Cuba as a romantic, idyllic, desirable, utopic mecca of ideals. If one can keep in check the political perspective/vantage point of the filmmaker, and not get carried away with fantasies that would lead one away from the reality of the horror/lack of freedom of expression/oppression/ incarceration of dissidents whose "crime" is setting up free access libraries, (these are just a sampling of the horrors...)/that has existed and progressively worsened since January 1959, then one can objectively say that this movie is art, and as art it is provocative and beautiful.
