You broke my heart, Fredo. You broke my HEART.
Moving stuff, fantastic performances from all involved in the trilogy throughout. Al Pacino played his part splendidly, from the charming but cunning young man to the slightly off the rails adult, and he seemed to really mature as a character throughout.
Got into The Godfather quite young, definitely before secondary school - probably around 7 or 8. Think it shaped my taste in cinema, and I'm definitely glad I got into it when I did.
