This film from the self called "Golden Age" of Mexican cinema is not only one of the most representative achievements of how high was the productions standards in those days, but also an spectacular shown of artistic precision. Filmed in the classic American way with a solid narrative timing based on economic shots and a strong screenplay, this movie shown how much director Alejandro Galindo learned in his pass by Hollywood aside with director Gregory LaCava. The plot is simple but full of heart and mind: a cleaning machine breaks the stability of a conservative family; the modern time has come to fall apart the strong 19 th century comfort. From this point the post revolutionary society enters in crisis: the sons will be raised against his parents to discuss the authority terms. The generational barrier has rise. "Una familia de tantas" is a must see film for all those who likes the best classic cinema and for those who wants to know better the history of Mexican modern urban society in the middle of 20 th century
