The Godfather I think the best movie I've ever seen is "The Godfather", which was based on the book with the same name, written by Mario Puzo. Indeed, its cast is compose by amazing actors (Marlon Brando, Al Pacino, Robert Duvall among others), and a brilliant director: Francis Ford Coppola. But that isn't all. The story flows naturally during you watch a military man behaved and adjusted to the social rules, who never affectionate to the criminal activities of his family before, becomes the Los Angeles Italian Mafia big boss. Finally, the movie also portrays Los Angeles in half of 20 century. A nice, but harmful, city where the economic depends on the criminal gangs activities.
