I strongly believe that the message Francis Ford Coppola and Mario Puzo were trying to say in these films is that family is the most important thing more than money or friendship. All the three Godfather films centre around the Corleone Family and in Godfather Part 2 Micheal asks his mother if u can lose ure family and she tells him u can never lose ure family. The lesson that is said is that family is everything and without it there would be no life as the Godfather Films wouldn't have been made how hey are surronding the emotional feelings of the Corleone Family
