I have heard from several Cubans that the documentary Sicko is a completely inaccurate picture of Cuban healthcare, that what they show in the film is the healthcare that is available only to the upper classes, what we in the USA might call "upper middle class" and up, and that the healthcare experience for the vast majority of average people is not like that at all.
Worth thinking about before you put too much stock in the film.
