At times the tried and true formula works best and this is certainly the case in "Two Sons of Francisco," a Brazilian box-office superhit that had the whole nation rushing to the theaters -- over 5.5. million.

Directed by publicity film and advert director Breno Silvera, it's a music biopic based on the lives of brothers duo Zeze di Camargo & Luciano, one of the most popular sertanejo (Brazilian country and western) musicians the country has known, selling something like 22 million CDs.

Subtlety goes out the window as Silvera hits that old nail again and again, gleefully rolling out every cliche in the book and manipulating audience tear ducts with the regularity of a plumber testing a water system.
