Movie: cinco de mayo

Order Description
With cinco de mayo we begin (sort of) and close our course subject: the Mexican Revolution. I see this battle as the predecessor character of Mexico’s Revolution, and ever since a defining disgrace for the country. However, I like this movie because we are presented with an image of Diaz that we did not see in our readings.

My question is: having watched this movie now, is Diaz a good guy or a bad one? Was he really a dictator? Feel free in answering my question. Any other issues you would like to mention or question, feel free to do so.

Unfortunately, the movie does not have English subtitles, so for those who do not understand Spanish this is your task: provide a brief research on this cinco de mayo event. Provide any dates and names so that your research complements the movie.
