MOVIES: Why do you think Godfather 3 sucked?

I actually preferred the third film to 'The Godfather: Part Two', which I felt suffered from spurious story-lines and an interminable length. For me, the melodrama of 'three' lent it thematic continuity with the masterful original and allowed for the successful evocation of Shakespearean catharsis (of the kind commonly associated with the playwrite's better tragedies) at the story's end.
