When you compare The Godfather to The Godfather, Part II, the only difference between the two films is the cast. There is no James Caan and Marlon Brando. Now, that doesn't make the movie worse, as most people would think. The storyline is interesting, yet very sad, although this movie is excellent, it is very sad. The Godfather, however, is inspiring due to Marlon Brando's beautiful and incouraging acting. Therefore, Al Pacino has to act twice as hard, and he's a great actor. He does a fantastic job. Every scene he acts he acts with passion and courage. Vito Corleone's childhood is also great, although the adaptation in the 1970's of The Godfather and The Godfather Part II, was called, The Godfather, A Novel of a movie, (I think). I watched that and it was the two Godfather's combined together. Vito Corleone's childhood from Part II is combined at the beginning of the movie. Amazing and terrific. Definetly worth watching.
