Andy Garcia and Mauricio Kuri in For Greater GloryFOR GREATER GLORY

To my considerable chagrin, before seeing For Greater Glory, I had no knowledge of the Cristero War that serves as the film's subject - a brutal conflict between devout Roman Catholics and the Mexican government that, in the late 1920s, claimed nearly 100,000 lives. Consequently, I thank director Dean Wright and screenwriter Michael Love for their two-and-a-half hour exploration of this years-long struggle, a movie that's intensely informative and sincere, and mostly engaging. If only it weren't also so sentimental, and so manipulative.
