I had the opportunity of watching this documentary earlier this year and I can't explain how amazing it is!!! I just found out it won the Sundance Film Festival award to best directing, and i'm incredibly glad because it truly is a great documentary.
It talks about Mexico's president in 1924, Plutarco Elias Calles, through the memories of his daughter, narrater by the great-grandaughter. It sort of introduces you to the history of Mexico's politics and how Calles affected present day citizens' view of the government. Really, if you have a chance to see it, please do! I especially recommend it because it is filmed in my hometown of Mexico City. Here is the actual synopsis of the film by POV.
P.S. Click on the picture to watch the trailer.

SYNOPSIS

Past and present collide as award-winning filmmaker Natalia Almada (Al Otro Lado, POV 2006) brings to life audio recordings she inherited from her grandmother, daughter of Plutarco Elías Calles, a revolutionary general who became Mexico’s president in 1924. In his time, Calles was called El Jefe Maximo (Foremost Chief). Today he is remembered as El Quema-Curas (Priest Burner) and as a dictator who ruled through puppet presidents until his exile in 1936. Airing during the centennial of the Mexican Revolution, El General moves between a daughter’s memories of her father as she grapples with history’s portrayal of him and the weight of that same man’s legacy on Mexico today. Winner of the 2009 Sundance Film Festival U.S. Directing Award: Documentary. A co-production of ITVS in association with Latino Public Broadcasting. A Creative Capital project.
