There was a movie on the Cristiada directed by a veteran of the production staff for the latter two LOTR movies, which of course was immediately bashed by those 'professional' critics who even bothered to watch it in the first place. Worth a watch, IMO. Of the Mexican internal conflicts where the bad guys won, that was definitely the most recent and will remain so, at least until the cartels finish toppling whatever facade of a government still exists entirely.
