There's no doubt that the subject matter of "For Greater Glory: The True Story of Cristiada" - the Cristeros War of Mexico in the late 1920s - could make for an interesting and even entertaining movie. But to tell the truth, I felt kind of unsatisfied at the end. One of the most expensive Mexican movies made (though low budget by Hollywood standards), I will say that the movie (for the most part) looks pretty good. But the movie is saddled with a substandard script. The movie is both too long and not long enough. It unfolds at a pretty slow pace, and there are a number of scenes that could have been eliminated. But at the same time, it doesn't go into detail enough on a number of important points. The motivations of the characters are more often than not vague, and there are a number of unanswered questions for those unfamiliar with this part of Mexican history. While I wouldn't call this movie terrible, it is unsatisfying. Though on a positive note, it will probably get you to do some research about this conflict.
