...the Bocchiccio story was the best "backstory" in the novel.
I couldn't agree more. What a great story. I think it's a shame that Puzo didn't insist with FFC that this backstory be included in the movie. Not only for the watcher to understand how Don Vito engineered Michael's safe return to the US, but also to educate the watcher as to how the Bocchiccio Family operated and their role in being professional hostages. I feel that it would have answered a lot of questions for those that didn't read the novel.
