The Godfather movies are considered among the movies ever made, but which Godfather movie is best? Based on Mario Puzo’s bestselling crime novel, Francis Ford Coppola’s The Godfather trilogy has had an indelible mark on cinema, changing the way in which mob dramas are made and perceived. In addition to stellar performances and taut narrative storytelling, The Godfather movie's success as a whole can be attributed to its underlying themes — mainly the warped version of the American Dream. An unforgettable manifesto on organized crime, The Godfather and The Godfather Part II, in particular, have been deemed prime representations of the gangster genre.
