The movie has everything you need. It shows what the mafia really does and why. It shows you the world on a different perspective. With the best actors of all time (Al Pacino and Robert De Niro). It shows the evolve of the characters Micheal and Vito a the best way. If you don't believe me look at the awards that the movie won. 6 Oscar's that is 1/4 of all the Oscars from that year.
