I suppose it's all a matter of taste and opinion as to which parts of the movie was most appealing.

I loved the whole movie, but in my opinion, I thought the Sicilian portion was a beautiful addition to the movie. Doesn't make me right or wrong, just my opinion.
Also, even tho we never knew Appolonia that well, I just can't believe she'd be so cold as to ignore the news Michael was given, had she heard it or suspected it was news of serious nature. Again my opinion for what it's worth. Like I said there is no right or wrong in these opinion questions.
